Product Description
Chamotte is produced by calcining selected fireclay at high temperatures, forming a stable mullite–corundum crystalline structure. It features high refractoriness, low thermal expansion, excellent thermal shock resistance, and good slag corrosion resistance. Chamotte is widely used in refractory bricks, castables, kiln furniture, ceramics, and foundry applications.
Key Properties
- High refractoriness
- Good thermal shock resistance
- Stable bulk density
- Low impurity content
- Excellent slag and corrosion resistance
- Good volume stability at high temperature
Typical Applications
- Refractory bricks and shaped products
- Monolithic refractories (castables, gunning mixes, ramming mixes)
- Kiln furniture and supports
- Ceramic kiln linings
- Steel foundry linings
- Incinerator linings
- Cement and glass industry furnaces
Advantages
- Stable mullite phase development
- Excellent sintering behavior
- Improved service life in thermal cycling
- Suitable for both dense and insulating refractories
