Dense zircon brick
- Description
-
Zircon brick is made from Australian zircon sand recycled aggregate, zircon powder, composite ultrafine powder, and special additives, formed under high pressure and sintered at high temperatures. It is mainly used in the bottom and upper structure of glass furnace melting pools, featuring strong resistance to glass liquid erosion and permeability, excellent thermal shock stability, superior high-temperature resistance to deformation, high compressive strength, and a high load softening start temperature.
