SiSiC is a high-performance ceramic material produced through a chemical reaction sintering process. It has become a critical material in aerospace, energy, electronics, and chemical industries, particularly for high-reliability applications under extreme conditions. Its properties and application areas are as follows:

Properties

High Strength and Hardness

Second only to diamond and cubic boron nitride in hardness, it offers excellent wear resistance, making it suitable for high-load working conditions.

High-Temperature Resistance

Capable of long-term use at temperatures exceeding 1600°C, with strong thermal shock resistance to withstand drastic temperature changes.

Corrosion and Oxidation Resistance

Exhibits superior resistance to acids, alkalis, salts, and molten metals, along with outstanding oxidation resistance.

Low Thermal Expansion Coefficient

Features low thermal expansion and dimensional stability, ideal for precision mechanical components.

High Thermal Conductivity

Thermal conductivity approaching that of metals ensures efficient heat dissipation, suitable for electronic device cooling.
