RSiC Plate

Semicorex RSiC Plate is a high-performance recrystallized silicon carbide ceramic flat plate designed for demanding thermal, mechanical, and chemical environments. Manufactured through a high-temperature recrystallization process, RSiC (Recrystallized Silicon Carbide) exhibits exceptional purity, excellent thermal stability, and outstanding resistance to corrosion and wear. These properties make RSiC plate an ideal solution for applications requiring reliable performance under extreme conditions.

Recrystallized silicon carbide is characterized by its unique microstructure, consisting of interlocked SiC grains without the use of sintering additives. This additive-free structure provides RSiC plate with excellent high-temperature strength retention and superior thermal shock resistance. Unlike conventional ceramic materials, RSiC maintains its mechanical integrity and dimensional stability at temperatures exceeding 1600 °C, making it particularly suitable for high-temperature furnaces, thermal processing equipment, and advanced industrial systems.

1. Exceptional Strength at Temperature

Because there is no glass phase or metallic silicon binder, RSiC does not suffer from "creep" or "sagging." Even at temperatures as high as 1,600°C to 1,650°C in oxidizing atmospheres (and higher in inert environments), our plates maintain their original shape and load-bearing capacity. This makes them the ideal choice for heavy-load batch processing in high-heat kilns.

2. Unrivaled Thermal Shock Resistance

Thermal cycling is the primary cause of failure for most ceramic plates. RSiC possesses a unique porous structure and high thermal conductivity (>30 W/m·K), which allows it to absorb and dissipate thermal stress far more efficiently than dense ceramics. Our plates can withstand rapid heating and cooling cycles that would cause alumina or quartz to crack instantly.

3. High Purity for Sensitive Processes

With an SiC content typically exceeding 99%, our RSiC plate are an excellent choice for applications where metallic contamination must be minimized. They are widely used in the production of high-purity electronic ceramics, powdered metallurgy, and specialized semiconductor components.

Strategic Applications

Our RSiC plate are designed for "Mission Critical" roles across several industries:

Kiln Furniture for Technical Ceramics: Used as setter plates for firing MLCCs, piezoelectrics, and high-voltage insulators where zero-warpage is required.

Semiconductor Processing: Acts as a high-purity heat shield or support plate in diffusion and annealing furnaces.

Solar Energy: Utilized in the sintering of solar-grade silicon components and high-efficiency cell processing.

Battery Materials: Ideal for the high-temperature calcination of cathode materials where chemical purity is paramount.
