Refractory Clay

Product Introduction：
Refractory clay is prepared by adding inorganic or organic binders to refractory powder. Based on the material of the refractory bricks, refractory powder with similar physical and chemical properties to refractory bricks is selected to meet the requirements of different refractory bricks.
 
Product Highlights:
1. Small shrinkage of heating line after baking;
2. Stable chemical properties;
3. Convenient construction.

Application:
It can be used for buliding refractory products.
