SICcast PLUS is a silicon carbide ceramic (SiSiC).

Silicon carbide ceramics are used when highest wear rates coincide with extreme usage conditions. These usage conditions may include extreme chemical exposure and temperatures up to 1100 °C. Silicon carbide ceramics are a tried and tested material for such applications.
Production methods common on the market make it very difficult to produce large, complex parts so far (e.g. by joining).
The new SICcast PLUS procedure is used to cast parts according to the tried and tested SICcast PLUS high-precision casting procedure at first. After demoulding, the resin share is broken down into carbon by pyrolysis and then converted to silicon carbide as well by silciation.
This novel procedure now makes it possible to produce large parts with highly complex forms and backcutting as well as large wall thickness differences.
