Cast ceramics: the raw materials alumina Al₂O₃, ZrO₂ and SiC are fused in a furnace and cast in moulds. This production process makes it possible to cast complex parts.
Advantages:
- perfect impact resistance
- thermal shock resistance
- abrasive wear resistance
- during the casting, metallic inserts can be placed
- adapted to frictional wear
Cast basalt
Cast basalt is a mineral product with high hardness.
The volcanic rock is milled and fused in a furnace at 1280°C and cast in moulds.
The surface is very smooth, so the product is well adapted for frictional wear.
