RSIC uses highly pure silicon carbide materials. They are produced by evaporation- coagulation and fired under high-temperature 2400℃ to get a highly pure ceramic with porous network structure. This material has an open porosity of approximately 11% to 15%, the grain size of approximately 100 pm, shrinkage behaviour at firing (no shrinkage occurs), and appliions (kiln construction).
Silicon Nitride Bonded Silicon Carbide Bricks Exploiting the material’s excellent stability and mechanical strength, nitrogen bonded silicon carbide bricks are used in a range of process furnaces and kilns such as the sidewalls of aluminium melting pots, the lower stack of blast furnaces, and as kiln furniture .

In addition, its high coefficient of thermal expansion is close to that of metals and glass, allowing forsterite to be joined or bonded to these materials reliably. With a low coefficient of thermal expansion and superior thermal shock resistance, this material is used for heat-resistant components, wire-wound resistive bobbins and electron tube components.
