Searching from applications: Characteristic of SiC

For refractory and ceramic structural materials

While traditionally used for refractory, SiC is recently starting to be as a ceramic structural material due to its wear resistance, corrosion resistance and high mechanical strength under high temperatures.
SiC is also used in various applications, including the driving part of mechanical seals, wafer chucks in semiconductor manufacturing and in Diesel Particulate Filters (DPF).

For refractory use
Compared to other refractory materials, SiC maintains greater strength under high temperatures. In addition to excellent heat resistance, it is long-lasting in shaped refractory, monolithic refractory and shelf board uses.

For Diesel Particulate Filters (DPF)
In recent years, environmental issues have become a global problem. SiC is used as an aggregate material in Diesel Particulate Filters to remove graphite in diesel vehicles.

For fine ceramic use
Making good use of wear resistance, corrosion resistance and high thermal conductivity, SiC can be used for some semiconductor manufacturing parts. We now offer our products with controlled SiC purity, particle size and precise particle distribution.
