Industrial Grade High-alumina Calcined Kaolin for Casting and Refractories(0-1 mm,1-3 mm,3-5 mm)

1. Production Introduction and Application


Calcined Kaolin is a mixture of inorganic nonmetal, calcined kaolin is calcined kaolin in sintering furnace to a certain temperature and time, the physical and chemical properties which has a certain change, in order to meet certain requirements.

The size of particles: 0-1mm,1-3mm,3-5mm,5-8mm,8-15mm,0-5mm,0-50mm can be used for refractories and casting material.


Calcined Kaolin with high purity is white. Kaolin whiteness, natural whiteness, and whiteness after calcination. For ceramic raw materials, the whiteness of calcined is more important, the higher the whiteness of calcined, the better the quality.


Ceramics, rubber, plastics, artificial leather, cement, refractory materials, chemical industry and agriculture are widely used.
