Features and Applications of Silicon Carbide Plate
Silicon carbide plates are mainly made of silicon carbide (SiC), which has exceptional wear resistance, high temperature resistance, corrosion resistance, and excellent dimensional stability with a Mohs hardness greater than 9(second only to diamond). Below are the main features and applications of silicon carbide plates.
- Excellent Heat Resistance
Silicon carbide plates offer outstanding heat resistance up to 1650°C without softening or deforming. Ideal for industrial kiln use.
- High Thermal Conductivity
Silicon carbide plates can quickly move heat, improving the overall heat efficiency in the manufacturing of daily-use porcelain, sanitary porcelain, high-voltage electric porcelain, and glass.
- Outstanding Thermal Shock Resistance
Silicon carbide plates can be used in high-temperature areas where temperature changes a lot, like in wafer processing furnaces.
- Low Coefficient of Thermal Expansion (CTE)
Used in components for high-precision optical systems and semiconductor wafer handling equipment for it expands and contracts minimally with temperature changes.
- Strong Corrosion Resistance
Silicon carbide plates can be used as lining plates in the chemical industry to resist heat and corrosive materials.
- High Wear Resistance
Silicon carbide plates can also be used as lining plates in industries like mining to resist strong wear from materials and make equipment last longer.
- Superior Impact Strength
Silicon carbide plates are more and more used in armor protection with very high hardness and strength.
- Extended Service Life
As replacement parts for some machine, silicon carbide plates help reduce maintenance and replacement costs because of their long service life.

Silicon carbide plates are expensive mainly because of their complex manufacturing process and high cost. They require ultra-high purity and micronized powders and the shaping and cutting processes need extremely high temperatures and specialized equipment. Moreover, the low yield rate during production, with a significant number of plates being discarded during manufacturing, further drives up the cost. Despite increased production capacity in some factories recently, the price of silicon carbide plates remains high due to the complex manufacturing process and significant waste rate.
Ordinarily, kiln tools are generally two to five years. However, the service life of silicon carbide plates with different processes varies due to the frequency of use, operation mode and furnace atmosphere.
are their benefits?
- Reaction Bonded Silicon Carbide/Silicon Infiltrated Silicon Carbide(SISIC): The silicon content in the material limits the maximum working temperature to 1380°C. Reaction-sintered silicon carbide has high strength, high hardness, high wear resistance, corrosion resistance, and good oxidation resistance and thermal shock resistance.
- Oxide Bonded Silicon Carbide(OSIC): It is a machine-pressed type with expansion gaps on the plate. The maximum working temperature is lower than 1450℃. It is mainly used in daily-use ceramic factories, and it is mainly made into plates and brackets.
- Recrystallized Silicon Carbide(RSIC): It is one of the few materials that can be used as a bearing under air conditions above 1500℃. Using its high strength and high thermal conductivity, the silicon carbide plate can be made very thin, effectively reducing the volume of the kiln, greatly reducing the loading ratio of kiln tools and porcelain pieces to be fired, improving the utilization rate of the kiln, and realizing the rapid firing of ceramics, doubling the kiln products and reducing the unit energy consumption of the kiln. The thermal conductivity is more than 5 times that of general silicon carbide refractory materials.
- Nitride Bonded Silicon Carbide(NSIC): The maximum use temperature is within 1450℃. NSiC is mainly used in daily ceramic factories, such as tableware, stoneware, sanitaryware, handmade pottery and porcelain, artistic ceramics, and high-voltage electric porcelain, and is also widely used in the metallurgical and chemical industries. And its thermal shock resistance is better than RSiC.
- Sintered Silicon Carbide(SSIC): SSiC is resistant to all chemicals. Because it does not contain metallic silicon in its structure, it can be used at temperatures up to 1650℃ without affecting its strength. It has good thermal conductivity and excellent mechanical properties. Due to the limitations of the production process, the production cost is the highest. The overall weight of the kiln car is much lighter.
