Clay powder refers to the calcined clay refractory raw material.
The appearance is white or nearly white, mixed with light yellow.
It is the main raw material used for producing clay fire lining products. Its main chemical components are Al2O3 and SiO2.
(1)High strength
(2) Low water absorption rate
(3) Good resistance to wear
(4)Good weathering resistance
Clay powder is mainly used for refractory materials, such as amorphous refractory materials and refractory bricks. When the operating temperature of kilns or thermal equipment is low, it can also be used as refractory powder
