tabular alumina for refractory

الوصف

Tabular Alumina is one type of high purity alumina shaped in both granular and power. It has good properties of high density, low porosity, high mechanical strength, extreme hardness, and durability. 
Tabular alumina has been widely used as the material of choice in unshaped and shaped high performance refractories used in a variety of industries (steel, foundry, cement, glass, petrochemical, ceramic and waste incineration). Other common non-refractory applications include its use in kiln furniture and for metal filtration.
