Specifications
Refractory zircon brickFive types: dense zircon brick,zircon brick,Zi-Cor brick,Zi-Mull brick,Semi-Zi brick
High quality refractory zircon brick
Our zirconia brick is made of α-Al2O3, partially stabilized zirconia and zirconium corundum clinker and other materials.
They are raw materials.
Then mixing → molding → drying → sintering(sinter at high temp in shuttle kiln), through these producing, then made into refractory zircon brick.
Feature
1.Dense crystal structure, high bulk density, high unit weight,
2.High mechanical strength at high temperature and normal temperature, good thermal shock resistance,
3.Small reheating contraction and high temperature peristaltic
4.Has a very high chemical stability and anti alkaline medium corrosion.
