Chamotte (Calcined Fireclay)
Chamotte, also known as Calcined Fireclay, is produced by calcining selected fireclay at high temperatures, forming a stable mullite–corundum crystalline structure. It offers high refractoriness, excellent thermal shock resistance, low thermal expansion, and strong slag corrosion resistance.
ZE XI MINERAL CO., LTD supplies high-quality chamotte for refractory bricks, castables, kiln furniture, foundry linings, and high-temperature industrial furnaces.
Key Properties
- High refractoriness and thermal stability
- Excellent thermal shock resistance
- Stable bulk density and volume stability

Typical Applications
- Refractory bricks and shaped products
- Monolithic refractories (castables, gunning mixes, ramming mixes)
- Kiln furniture and kiln linings
- Steel foundry linings
- Incinerators, cement and glass furnaces
