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.
