Silicon carbide raw materials (normally silicon carbide aggregate), Silicon carbide (SiC) is a synthetic, semiconducting fine ceramic that excels in a wide cross-section of industrial markets. Manufacturers benefit from an eclectic offering of silicon carbide grades due to the availability of both high-density and open porous structures.
Silicon carbide raw materials (normally silicon carbide aggregate), Silicon carbide (SiC) is a synthetic, semiconducting fine ceramic that excels in a wide cross-section of industrial markets. Manufacturers benefit from an eclectic offering of silicon carbide grades due to the availability of both high-density and open porous structures. Combined with the material’s outstanding high-temperature strength and thermal shock resistance, alongside inherently impressive mechanical properties, silicon carbide is one of the most versatile refractory ceramics worldwide. Normally the material of Silicon Carbide as the aggregate is in grain status or in powder status.
Silicon carbide is formed in two ways, reaction bonding, and sintering. Each forming method greatly affects the end microstructure. Reaction-bonded SiC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming more SiC which bonds the initial SiC particles.
Sintered SiC is produced from pure SiC powder with non-oxide sintering aids. Conventional ceramic forming processes are used and the material is sintered in an inert atmosphere at temperatures up to 2000ºC or higher. Both forms of silicon carbide (SiC) are highly wear-resistant with good mechanical properties, including high-temperature strength and thermal shock resistance.
There are two types of SiC materials, one is in black, and the other is in green.
1. Low density
2. High strength
3. Good high-temperature strength (reaction bonded)
4. Oxidation resistance (reaction bonded)
5. Excellent thermal shock resistance
6. High hardness and wear resistance
7. Excellent chemical resistance
8. Low thermal expansion and high thermal conductivity
