Extreme-Environment Silicon Carbide Ceramic Plates for Industrial Systems

ADCERAX® Silicon Carbide Ceramic Plates Resolve Industrial Heat, Wear, and Corrosion Challenges

ADCERAX® Silicon Carbide Ceramic Plates support industrial operations where extreme heat, abrasive flow, and corrosive chemical exposure must be managed simultaneously, enabling reliable performance in equipment subjected to continuous and demanding processing conditions.

• High-Load Thermal Carriers for Continuous Sintering Lines

  ✅Key Advantages

  1. High-Temperature Flatness Stability

  The plate maintains structural integrity across 1300–1600°C operating windows due to its 4.2–4.5×10⁻⁶ K⁻¹ thermal expansion coefficient. This minimizes warping during rapid cycling between heating and cooling zones.

  2. Superior Flexural Performance Under Load

  With ≥350–450 MPa flexural strength (SSiC), the plate withstands repeated mechanical loading from stacked sintering payloads. This prevents progressive bending deformation often seen with alumina or metallic carriers.

  3. Uniform Heat Transfer Support

  Its 120–200 W/m·K thermal conductivity enables consistent thermal gradients along the sintering path. This supports stable heating profiles even when furnace zone temperatures fluctuate significantly.

  ✅ ️Problem Solved

  Continuous sintering furnaces in ceramic and metallurgical production encountered plate distortion after several operational cycles, especially around thermal transition sections where temperatures changed abruptly. Metal carriers exhibited bending after repeated exposure near their structural limit, and alumina plates developed uneven curvature, disrupting uniform heating. ADCERAX® Silicon Carbide Ceramic Plate maintained flatness in these environments due to its low thermal expansion and high mechanical rigidity, even at temperatures above 1300°C. A European furnace operator reported that thermal profile deviations along the sintering line were reduced after replacing warped carriers, improving process consistency. Over several production cycles, the SiC plates demonstrated steady structure and minimized interruptions for plate inspections or replacements.

• Abrasive Transfer Systems for Mining and Bulk Material Handling

  ✅Key Advantages

  1. Extreme Abrasion Resistance in High-Impact Zones

  The plate’s Mohs 9 hardness and ≤0.1% porosity resist the erosive effects of mineral fines and crushed aggregates moving at high velocity. This mitigates the rapid surface removal typically seen in steel liners.

  2. Dimensional Stability in Elevated Temperatures

  With thermal resistance up to 1300–1600°C, the plate retains surface rigidity when steel softens or polymer liners deform under elevated thermal loads. This ensures predictable material flow in transition zones.

  3. Reduced Turbulence and Dust Generation

  The plate’s dense microstructure and stable surface condition help maintain smooth transfer paths over long operating cycles. This reduces turbulence that otherwise increases dust load and contaminates downstream equipment.

  ✅ ️Problem Solved

  Mining operations using steel liners in transfer chutes saw accelerated wear when processing abrasive ores and aggregates, leading to uneven surfaces that increased turbulence and reduced flow uniformity. Polymer liners could not maintain rigidity when the chute temperature rose during continuous operation, resulting in deformation and premature replacement. After adopting ADCERAX® Silicon Carbide Ceramic Plate, the transfer system maintained a consistent surface condition due to its high hardness and thermal stability, even during extended operation. The plant recorded fewer interruptions for liner removal and cleaning, and flow stabilization improved downstream classification consistency. Over time, the reduced wear rate helped sustain a more predictable material handling cycle.

• Acid-Gas and Chemical Tower Internals for Corrosive Processing Systems

  ✅Key Advantages

  1. Resistance to Acidic and Alkaline Vapors

  The plate remains chemically stable in environments containing H₂SO₄, HCl, HNO₃, and alkaline vapors such as NaOH and KOH. This prevents the pitting and surface breakdown that metals experience under similar conditions.

  2. Structural Integrity Under Thermal–Chemical Coupling

  Its mechanical strength of ≥2200 MPa compressive capacity enables sustained load-bearing performance when temperature and corrosive gas concentration fluctuate simultaneously. This avoids the softening and rigidity loss observed in polymer-based internals.

  3. Non-Reactive Behavior in High-Chlorine Conditions

  The inertness of SiC under high-chlorine atmospheres prevents chemical reactions that compromise internal tower components. This ensures predictable stability during extended exposure to corrosive streams.

  ✅ ️Problem Solved

  Chemical processing towers handling acidic condensates and chlorinated vapors experienced surface degradation when using metal internals, with corrosion pits forming after repeated exposure to combined thermal and chemical stresses. Polymer-based panels distorted and lost mechanical rigidity when temperatures increased, further complicating structural reliability. ADCERAX® Silicon Carbide Ceramic Plate maintained dimensional and chemical stability under these mixed conditions due to its corrosion-resistant SiC matrix and high compressive strength. A processing facility reported significantly fewer internal panel replacements after switching to SiC, noting improved operational continuity across cycles involving fluctuating gas compositions. The stability of the plates reduced inspection frequency and helped maintain consistent internal flow distribution.

Practical User Guide for ADCERAX® Silicon Carbide Ceramic Plates

The Silicon Carbide Ceramic Plates require proper inspection, handling, installation, and maintenance to ensure consistent performance in demanding thermal, abrasive, and corrosive industrial environments.

• Pre-Use Inspection Requirements

  1. Check for Surface Integrity:
  Inspect the plate surfaces under adequate lighting to confirm the absence of cracks, edge chipping, or structural abnormalities. This ensures stable load support during thermal cycling. Any visible defect should be addressed before installation to prevent unexpected structural failure.
  2. Confirm Cleanliness Before Use:
  Wipe the plate surface with a clean, lint-free cloth to remove dust or particulates accumulated during storage or transportation. Contamination can alter thermal transmission or create localized stress points during heating. Maintaining a clean surface helps preserve long-term dimensional stability.
  3. Verify Material Labeling:
  Ensure the identification label or batch marking is intact and corresponds to the required SiC grade. Proper traceability supports accurate configuration in high-temperature or chemical processing environments. A clear label also helps maintain a consistent replacement strategy across production cycles.

• Safe Handling and Transportation Guidelines

  1. Use Controlled Handling Movements:
  Transport the plate using both hands or mechanical support to avoid collision with hard surfaces. Sudden impact can induce micro-fractures not visible during routine checks. Controlled movement reduces the risk of load-bearing degradation during service.
  2. Avoid Exposing the Plate to Unstable Loads:
  Do not stack uneven weights directly on the plate during internal transfer. Excess point loading may create bending stress, especially before installation. Maintaining uniform support prevents premature mechanical distortion.
  3. Keep the Plate Away from Moisture During Transfer:
  Although SiC is chemically stable, prolonged moisture contact during handling can affect surrounding packaging and installation preparation. A dry environment ensures safe transition into high-temperature systems. Proper moisture control supports consistent operational reliability.

• Installation Best Practices for Industrial Systems

  1. Ensure Stable Mounting Surfaces:
  Verify that the support frame or mounting zone is flat, rigid, and free from embedded debris. Uneven contact may cause localized stress concentration during heating cycles. A stable platform preserves thermal uniformity and flatness retention.
  2. Maintain Proper Gap Allowance in Thermal Systems:
  Position the plate with sufficient clearance from adjacent components to accommodate natural thermal expansion. This prevents frictional wear when operating at elevated temperatures. Adequate spacing minimizes the risk of edge-related structural interference.
  3. Confirm Secure Placement Before Operation:
  Check that the plate sits correctly within its holding structure before initiating thermal or chemical processes. Misalignment can lead to vibration or unexpected mechanical stress. Proper alignment supports predictable process stability.

• Storage, Maintenance, and Service Life Guidelines

  1. Store in a Dry, Ventilated Environment:
  Keep plates in moisture-free conditions with adequate airflow to prevent long-term environmental stress on packaging materials. Avoid proximity to corrosive vapors or volatile chemicals. Controlled storage maintains steady performance characteristics.
  2. Follow Scheduled Cleaning Routines:
  Use non-reactive cleaning tools to remove process residues after each operational cycle. Avoid abrasive brushes that might alter the surface texture. Regular cleaning helps retain optimal heat transfer performance.
  3. Document Service Cycles for Replacement Planning:
  Record operating hours, temperature exposure, and any observed physical changes. Tracking these factors allows more accurate planning for replacement intervals in continuous production environments. Documentation helps maintain predictable maintenance control.
