Product Introduction

Zircon bricks are made of zirconia and zirconia corundum cement as raw materials, mixed with rubber, molded, dried, and fired in a shuttle kiln at high temperatures.

Features

1.High molecular structure density.
2.High bulk density.
3.Good thermal shock stability.
4.Alkali and corrosion resistance.

Application

Zircon bricks are mainly used in alkali glass, borosilicate glass pool kiln bottom, upper space brick, brick hook, gap brick, flow slot brick, thermocouple brick and observation hole brick and other parts.
