Tabular Alumina

Process Of Production:

Tabular Alumina (TA) is a pure sintered a α-alumina materials that has been fully densified by rapid-sintering without the use of sintering aids at temperature in excess 1900℃. Tabular Alumina has characteristic large, well developed hexagonal tablet shaped α-alumina crystals of up to 200μm length. The excellent thermal volume stability and thermal shock characteristics can be attributed to its specific microstructure: low open porosity and large crystals with closed spherical pores, which are entrapped upon re-crystallization during rapid-sintering.

Product Performance:

Superhigh temperature shaft kiln sintered tabular alumina that takes alumina as raw material is molded by milling and drying; on condition of quick warming and cooling in superhigh temperature shaft kiln, it becomes lots of tight column crystal and the dimension of crystal is among 30-200um; there are lots of alumina corundum that has high purity with lots of closed micro-holes.

The special producing technology of this product determines its special performance: high fire proof; high corrosion proof; high scour proof; high stability of temperature shock; good tension and tenacity; stable chemical stability. It is one kind of excellent insulation raw materials for fire-proof, porcelain and electric instruments; meanwhile, it is also excellent material for milling tool and polishing milling.

Application:

 
● Tabular alumina is the perfect refractory raw material.
● Tabular alumina can replace fused alumina and white fused alumina in some application.
● Tabular alumina can use in kiln furniture and for metal filtration.
● Tabular alumina can be used in a variety of industries, including steel, foundry, cement, glass, petrochemical, ceramic and waste incineration.
