Description of Zircon Brick:
Zircon brick is an acidic refractory material with a series of excellent properties such as strong slag resistance, low thermal expansion, thermal conductivity decreases with increasing temperature, high load softening temperature, good wear resistance, good thermal shock stability, and not easily wetted by metal liquids.
