Silicon Carbide Refractory Plate
Silicon carbide refractory plate is a kiln lining plate with excellent fire resistance and wear resistance. It is often used in working environments that carry and transfer heat and chemicals under high temperature, high pressure and chemical corrosion conditions. Silicon carbide setter plates are mainly made of silicon carbide and silicon nitride materials, with high bulk density and fire resistance temperature, low thermal conductivity, and are not easy to affect the temperature distribution of the device.
Production Processes: OSiC/SSiC/NSiC/SiC/RBSiC(SiSiC)/RSiC.
Dimensions/Shape: Any size (max 1200×800mm) and shape (rectangle, circle, special cutouts) via CNC machining.
Craft Tailoring: Adjust bonding agents, sintering cycles, and surface treatments for your exact process parameters.
After-Sales: Technical consultation, installation guidance.
Features:
Fire resistance and wear resistance: Silicon carbide setter plates can work stably under high temperature, high pressure and chemical corrosion conditions, and have excellent fire resistance and wear resistance.
Anti-oxidation performance: It can work stably in oxidizing and reducing atmospheres, and the number of turnovers can reach more than 500-1000 times.
High temperature compressive and flexural strength: It has high strength and good compressive resistance, and can be used for a long time at high temperature without deformation.
Resistance to rapid cooling and heating: It has good resistance to rapid cooling and heating, and is not easy to crack during use. Wide operating temperature range: can be used in the range of 800℃-1400℃.
Silicon carbide plate with alumina coating can effectively reduce material wear and extend service life by forming a protective layer of alumina on the surface of silicon carbide. At the same time, the acid and alkali resistance of alumina can block the erosion of silicon carbide by external media and improve the corrosion resistance of the material. In addition, alumina has good insulation properties, which can isolate current or heat conduction and avoid the loss of electrical or thermal properties.
