With the increasing demand for high-performance materials in high-tech fields, the market outlook for silicon carbide special ceramics is promising, particularly in electronics, aerospace, automotive, and chemical industries.

Silicon carbide special ceramics have excellent chemical stability, resisting corrosion from most acids, alkalis, and organic solvents, and maintaining good performance at high temperatures.

Due to their high hardness and brittleness, processing usually involves diamond tools or laser machining techniques, including drilling, grinding, cutting, and polishing.

Main physical properties include high hardness (Vickers hardness of 2000-3000 HV), high density (3.1-3.2 g/cm³), low thermal expansion coefficient (4.0×10⁻⁶/K), and high thermal conductivity (120-200 W/mK).

Manufacturing processes typically include powder metallurgy, hot pressing sintering, and reaction sintering, forming dense ceramic materials through high-temperature sintering of silicon carbide powders.

Silicon carbide special ceramics can operate at temperatures up to 1600°C in air and even higher in an inert atmosphere or vacuum.

Disadvantages include high brittleness, difficulty in processing, high manufacturing cost, and susceptibility to brittle fracture at low temperatures.

Advantages include high hardness, high wear resistance, high temperature resistance, oxidation resistance, good chemical stability, low thermal expansion coefficient, and excellent thermal conductivity.

Silicon Silicide Specialty Ceramics is a high-performance ceramic made of silicon silicide (SiC) material with high hardness, high abrasion resistance, high temperature resistance and good chemical stability, which is widely used in aerospace, automotive manufacturing, electronics and chemical industries.

Main applications include wear-resistant components, high-temperature structural materials, electronic packaging materials, chemical equipment, mechanical seals, and semiconductor manufacturing equipment.
