Recrystallized Silicon Carbide Ceramic Three Hole Slotted Plate Optimized for Industrial High Temperature Kiln Furniture and Sintering
The Recrystallized Silicon Carbide (RSiC) Three-Hole Slotted Plate is a premium kiln furniture solution engineered for high-temperature sintering and firing applications. Manufactured from high-purity, highly active SiC raw materials through an ultra-high-temperature recrystallization process (exceeding 2200°C), this advanced ceramic plate delivers exceptional performance in the most demanding thermal environments.
The "three-hole slot" design enables efficient product loading, improved airflow, and enhanced thermal uniformity during the firing process, making it an ideal choice for modern industrial kilns.
- Ultra-High Purity - SiC content ≥99%, with no sintering aids or secondary phases. This binder-free composition eliminates contamination risk for high-value products requiring strict purity control.
- Excellent Thermal Shock Resistance - Unique recrystallized microstructure and high thermal conductivity withstand rapid temperature changes without cracking. Rated "Very Good" in thermal shock performance.
- High-Temperature Strength Retention - Maintains mechanical integrity at extreme temperatures with flexural strength at 1200°C (100-110 MPa) higher than at room temperature (90-100 MPa).
- Superior Thermal Conductivity - Thermal conductivity of 35-36 W/m*K at 1200°C enables rapid and uniform heat distribution, reducing thermal gradients.
- Low Thermal Expansion - Coefficient of thermal expansion of only 4.6 * 10⁻⁶/K up to 1200°C minimizes dimensional changes during heating and cooling.
- Lightweight Design - Bulk density of 2.65-2.75 g/cm³ reduces structural load on kiln furniture systems, enabling lighter kiln car designs and energy savings.
- Excellent Oxidation Resistance - Forms protective SiO₂ surface layer in oxidizing atmospheres, preventing further degradation and extending service life.
- Long Service Life - Combines high-temperature strength, creep resistance, and oxidation resistance for extended operational lifespan under continuous thermal cycling.
