Tabular Alumina

  • 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.
Tabular Alumina
  • 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.
