Silicon carbide plates are engineered for stable performance under high thermal loads, offering excellent dimensional stability, oxidation resistance, and mechanical strength. Ideal for industrial kilns, vacuum furnaces, and ceramic sintering lines.

Silicon Carbide Plates Advantages

  • High Temperature Resistance: Withstands up to 1600°C continuous operation, suitable for high-temperature kilns and vacuum furnaces.
  • Dimensional Stability: Low thermal expansion (≤ 4.5×10⁶⁻⁶/K) prevents cracking during rapid heating and cooling.
  • Precise Flatness: Flatness ≤ 0.3 mm/m and tolerances ± 0.2 mm ensure uniform sintering results.
  • Reusable Over 50 Cycles: Optimized for long-term use in repeated thermal cycles, reducing replacement costs.
  • Multi-industry Compatibility: Used in sintering, heat treatment, catalyst support, and lab-scale thermal processing.

Applications of SIC Plates

1: Heat Treatment Plant SiC plates placed in a vacuum furnace floor distribute thermal load and resist sagging after repeat cycles (10+ uses per plate verified in NiCr processing). Clients report stable thermal uniformity and no warping after 100+ hours of continuous use at 1500°C.

2: Ceramic Sintering Line Used as setter trays to support zirconia or alumina green bodies during sintering. Clients confirm that a flatness variation of less than 0.3 mm is critical for multilayer sintering uniformity.

3: Catalyst Support Frames. In oxidation-sensitive conditions, reaction-bonded SiC plates act as chemically inert support stages. Effective even under aggressive catalyst reactions.

Usage Instructions for SIC Plates

  • Ensure uniform thermal ramp-up to prevent local stress.
  • Clean using a soft brush and an alcohol-based solution after each cycle.
  • Avoid direct contact with molten metals or corrosive particles.
  • Store in dry, sealed containers between 5°C-35°C to avoid moisture-induced stress.
  • ⭐️⭐️⭐️⭐️⭐️
    The performance remains stable under high-temperature conditions, with no deformation or cracking issues, thanks to the ceramic robotic arm we purchased from Adcerax.

  • ⭐️⭐️⭐️⭐️⭐️
    The wear-resistant ceramic balls have a low breakage rate, high grinding efficiency, and do not affect the whiteness of the material
