Fused Mullite
HIGH ALUMINA content with the HIGH SHOCK RESISTANCE
ALTUS is an electrofused products manufacturer. Our fused mullite is obtained from the electric arc furnace fusion of high purity raw material. The produced mullite possesses excellent thermal shock resistance and resistance to deformation under load due to the low coefficient of thermal expansion. Our fused mullite is available in many sizes from macrogrits to microgrits.
Advantages:
- Low thermal expansion
- Excellent thermal shock resistance
- Excellent hot strength under load
- High resistance to spalling or corrosion
Applications:
- Refractories for glass and steel industries
- Shell building material for investment casting
- Kiln furniture
- Spark plug bodies
- Ceramic pressure casting tubes
- And many other applications
