Silicon Carbide (SiC) has properties that are strikingly similar to diamond: it is one of the lightest, hardest, and strongest technical ceramic materials, with excellent thermal conductivity, acid resistance, and low thermal expansion. Silicon Carbide is an excellent material to use when physical wear is a concern, making it suitable for a wide range of applications.
Wintrustek produces Silicon Carbide ceramics using two methods: sintering and reaction bonding.
Sintered SiC (SSiC) is made from pure SiC powder and non-oxide sintering aids. The material is sintered in an inert atmosphere at temperatures of up to 2000 °C or higher using standard ceramic forming techniques.
Reaction-Bonded SiC (RBSiC or SiSiC) is formed by mixing liquid silicon with penetrating compacts of SiC and carbon. The silicon reacts with the carbon, producing more SiC and binding the original SiC particles together.
Silicon Carbide (SiC) in both forms is highly wear resistant and has excellent mechanical properties.

Silicon carbide is generally used in the ceramic industry, but silicon carbide products can also be used in the industrial industry. The characteristics of silicon carbide refractory plate are because it is outstanding in all aspects, has good wear and tear resistance, and strong bearing capacity.
The industrial application of silicon carbide sheets is very extensive and environmentally friendly.
The role of SiC kiln furniture and the basic characteristics of kiln furniture materials:
- kiln furniture is a special refractory material, and kiln furniture is an indispensable high-temperature auxiliary material product in the ceramic industry, refractory material industry, abrasive industry, and other industries.
- According to the general requirements of ceramic products and the characteristics of kilns, kiln furniture materials must have the following basic properties: high strength, high hardness, high wear resistance, corrosion resistance, good oxidation resistance, and thermal shock resistance.
- Silicon carbide ceramics have excellent characteristics such as high mechanical strength, high-temperature resistance, strong oxidation resistance, good thermal stability, large thermal conductivity, and other excellent features.
