Chamotte Suppliers and Manufacturers

In AMTC we are engaged in processing, supplying, and exporting of Calcined Kaolin namely for porcelain industry, sanitary ceramics, ceramic tiles, refractories, iron & steel, chemistry and further applications. As a leading Supplier and Exporter of Chamotte (China Clay), We ensure that our clay and Minerals are made as per the international standard and norms. Packed in high quality packaging materials, our Kaolin is offered at very cost effective prices, without compromising outstanding quality and purity.

Chamotte is a natural material having mullite as major phase with excellent refractory properties. Ashapura’s Chamotte aggregates are manufactured from natural high quality clays having minimum impurities and alkali metals. Chamotte products have high purity, low porosity and optimum thermal stability. Key features of the products are dense microstructure, homogenous granulometry and highly crystalline mullite phase.

Chamotte Calcined kaoline We have calcined kaolin :calcination of crushed raw kaolin is done in a modern rotary kilnwith high efficiency . The fired kaoline grains have high density and volume stability .The chemical constitution and properities of the calcined kaolin grains are illustrated in the following table.

Descriptions: Chamotte refractory block is made from high quality calcined fireclays. It is widely used in float glass furnace bottoms and in multi-course furnace bottoms. Its glass contact qualities. Also make it suitable for day tanks and other special glass contact applications. Applications: Chamotte brick is mainly used for furnace and hot blast stove, furnaces of metallurgic, Building material, glass, ferrous metal etc.

Descriptions: Insulation brick is made from high purity refractory clays and other raw materials, with light Weight and mini-porosity well distributed. It has advantages of low thermal conductivity, low Heat storage, high spalling resistance, high hot compressive strength, how iron oxide and Alkali flux content, accurate dimensions. Applications: It is widely used for insulating layer and lining of industrial kilns & furnaces.
