Tabular Alumina are high-purity sintered alpha-alumina spheres (in various sizes).Tabular alumina has been fired at extremely high temperatures(>1900℃) to reduce porosity to a very low level.this high-temperature process leads the growth of large plate-like, alpha-alumina crystals giving”tabular”alumina its name.Tabular Alumina Balls are carefully selected before packaging for size control,roundness and smooth surface.
Tabular Alumina Usage:
1.Tabular alumina is the perfect refractory raw material.
2.Tabular alumina can replace fused alumina and whie fused alumina in some application.
3.Tabular alumina can use in kiln furniture and for metal filtration.
4.Tabular alumina can be used in a variety of industries, including steel, foundry, cement, glass, petrochemical, ceramic and waste incineration.
