Description
Product introduction
 
The main material of phosphate wear-resistant bricks is dense super or first-grade bauxite clinker. Its binder is phosphoric acid solution or aluminium phosphate solution. After semi-dry press forming, chemical bonded refractories are made by heat treatment at 400-600 C. It belongs to non-fired brick. In order to avoid the shrinkage of products in high temperature, it is necessary to introduce kyanite, sillimanite, pyrophyllite and silica into the ingredients.
