Sintered Silicon Carbide SSiC

Sintered-Silicon-Carbide–SSiC.jpg

SSiC is formed by bonding together the crystals of alpha silicon carbide (α-SiC), which form at very high temperatures.


It’s hardness is second only to that of diamonds, and is highly resistant to granular abrasion. The high purity of our ceramics (>98% SiC) also means they can withstand contact with the acidic and alkaline substances that machine components come in contact with in the chemical industry.


They can also withstand temperatures as high as 1650°C and are resistant to the oxidization effects that typically occur at high temperatures with other materials.

SSiC is one of our most important products. Its mechanical performance is close to that of high-pressure silicon carbide (HP-SiC), while its structural machinability is even higher than that of HP-SiC.


Its low cost means it is well-suited to mass production, while its high degree of machinability makes it suitable for complex designs. SSiC is particularly suitable for use in high-efficiency machine components such as glandless pumps and magnetic drive pumps, where other materials will rust or erode over time, or deform due to inadequate durability or resistance to heat.


The use of SSiC-based components reduces operational costs, as components do not require frequent replacement.
