Tabular alumina is sintered corundum from the shaft furnace plate of very high temperature. Take alumina as molded raw material by grinding and drying; With the fast heating and cooling condition in the shaft furnace, it becomes a bunch of tight column glass and the glass dimension is between 30-200um; Large quantity of alumina corundum that has high purity and many closed microholes.
Property: low porosity, high fire resistance; High resistance to the corrosion; Abrasion high resistance; high temperature shock stability; good tension and toughness; stable chemical stability.
1.
Tubular alumina is the perfect refractory raw material.
2. Tubular alumina can replace white fused alumina in some applications, and have much better properties.
3. Tubular alumina can be used in oven furniture and for metal filtration.
4. Triangular alumina can be used in a variety of industries, including incineration of steel, cast iron, cement, glass, petrochemical, ceramic, and waste.
