- The selected raw materials to make Mullite ball is fired at a high temperature, making the structure of this product dense.
- Mullite ball is an artificial sand with extremely stable quality due it being made of mullite crystals.
- This product is made by firing spherical granules, not by crushing.
- This product has the following advantageous chemical and physical properties:
- Large grain size, enabling sieving.
- High air permeability
- High refractoriness (SK37, 1825°C)
- High resistance to crush
- Little thermal expansion
- Excellent in fluidity and filling efficiency owing to being spherical
