Specification of Tabular Alumina
Character & uses
Super high temperature shaft kiln sintered plate corundum that takes alumina as raw material is molded by milling and drying; on condition of quick warming and cooling in super high 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 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.
