Product Introduction

Corundum bricks refer to refractory products with Al2O3 content greater than 90% and corundum as the main crystal phase. Corundum bricks can be pided into sintered corundum bricks and fused corundum bricks.

Features

1.Good chemical stability. 2.Good acid and alkali resistance and slag resistance. 3.Good corrosion resistance to metal and glass liquid.

Application

Corundum bricks are mainly used in the steel industry, non-ferrous smelting industry, carbon black industry, petroleum industry, chemical industry, fertilizer industry, etc.
