After integrating ADCERAX® Magnesia Stabilized Zirconia Ceramic Plate as an inner lining, surface degradation dropped by 98%, with no measurable mass loss after 500 hours of mixed chlorine and brine contact at 420 °C. The replacement cycle extended beyond one year, reducing maintenance costs by approximately USD 18,000 annually.

Handling and Usage Guide for Magnesia Stabilized Zirconia Ceramic Plate

To ensure maximum performance and product longevity, it is essential that MSZ Ceramic Plate is handled, installed, and maintained in alignment with best practices. This guide outlines key precautions and usage tips to help customers avoid common pitfalls in real-world industrial operations.

• Storage and Environmental Conditions

  1. Store the plates in a dry, low-humidity environment, ideally below 60% RH, to prevent moisture absorption or surface contamination before use.
  2. Avoid exposure to rapid temperature fluctuations during storage, especially if moved between cold and hot zones, as this may induce internal stress.
  3. Stack vertically using spacers or foam, ensuring the surfaces are not directly contacting each other to avoid scratches or corner chipping.

• Installation and Mounting Considerations

  1. Use flat and evenly supported bases when installing plates into sintering lines, reactors, or cabinets to avoid bending stresses and premature warping.
  2. Avoid overtightening mechanical fasteners or clamps, as local pressure points may lead to microcracking or eventual failure.
  3. When used in high-load applications, ensure the plate's bearing surface is clean and aligned to distribute force uniformly across its structure.

• Thermal Cycling and Operating Safety

  1. Preheat plates gradually when operating in systems exceeding 800 °C, aiming for a controlled ramp-up rate under 5 °C/min whenever possible.
  2. Never subject a cold plate to sudden contact with a hot surface, especially in sintering or heating chambers, as it may cause cracking from uneven expansion.
  3. If used in a cycling furnace or kiln, allow a cool-down period before moving or re-handling to reduce fracture risks.

• Transport, Handling, and Reuse

  1. Always transport the plates in foam-padded cartons or crates, with corner protectors and vibration-dampening material to prevent edge breakage.
  2. Do not stack unprotected plates on hard floors or metal surfaces, even briefly, to avoid micro-abrasions or contamination.
  3. After thermal use, inspect for signs of surface erosion, color change, or mechanical fatigue before reusing in any critical application.

FAQs — Technical Insights on Magnesia Stabilized Zirconia Ceramic Plate

1. Q1: Why is MSZ Ceramic Plate preferred for high-load environments?
   It features compressive strength exceeding 2000 MPa, making it ideal for applications requiring sustained mechanical pressure. Its dense microstructure resists deformation and surface wear during dynamic loading. This ensures longer operational life compared to conventional alumina or steel-based supports.

2. Q2: How does MSZ Ceramic Plate perform under thermal cycling?
   The plate withstands over 50 rapid heating and cooling cycles between 200 °C and 1000 °C without cracking. Its stabilized crystal structure prevents phase transformation, maintaining dimensional accuracy. This provides reliable thermal shock resistance in furnaces, kilns, and sintering equipment.

3. Q3: What makes MSZ Ceramic Plate effective in corrosive chemical environments?
   Its MgO-stabilized zirconia matrix resists degradation from acids, alkalis, and salts. Laboratory tests show less than 0.05% weight loss in 10% H₂SO₄ and NaOH exposure for 72 hours. This ensures stable performance for reactor linings and corrosion-prone processing zones.

4. Q4: Can MSZ Ceramic Plate be used in electrical insulation systems?
   Yes, it offers volume resistivity above 10⁸ Ω·cm and a dielectric strength greater than 10 kV/mm. These properties prevent electrical leakage even in humid or high-temperature environments. The non-magnetic nature also eliminates interference in sensitive control systems.

5. Q5: How does the low thermal conductivity of MSZ Ceramic Plate benefit users?
   With a thermal conductivity of only 2.5 W/m·K, it acts as an efficient heat barrier. This minimizes heat transfer to adjacent components, improving energy efficiency. The result is better thermal isolation and reduced heat loss in processing equipment.
