Tabular Alumina

Tabular Alumina Corundum (tabular corundum) Application

  • Refractory raw material
  • Replace fused alumina and white fused alumina
  • Klin furniture and metal filtration.
  • Be used in a variety of industries, including steel, foundry, cement, glass, petrochemical, ceramic, and waste incineration.

WHAT IS TABULAR ALUMINA

Tabular alumina (tabular corundum) is a white powder or group of particles made of pure Alumina corundum. In modern shaft kilns, we sinter this crystalline form of alpha alumina (previously palletized to balls of 25 mm in diameter) until it fully contracts at around 1750ºC, creating this thick, high-density crystal with 99.2% of alpha AI2O3 in its structure. Then we crush it, mill it, and sieve it to standard sizes (before this process it’s relatively big: 50 – 200 µm).

We have two white tabular alumina production lines through which we stock up with 50000 tons of it —each ton is as good as the previous one, meeting and even beating national standards when it comes to performance.

Granule:

0 – 0.5 mm, 1.0 – 3.0 mm, 3.0 – 5.0 mm, 5.0 – 8.0 mm

Fine:
40 mesh, 60 mesh, 80 mesh, 120 mesh, 150 mesh, 180 mesh, 200 mesh,  240 mesh, 270 mesh, 325 mesh

alumina corundum application

We distribute white tabular alumina to our customers in the steel, foundry, glass, ceramic, cement, petrochemical, ceramic, cement, and refractory industries. With alumina corundum, they build and export bricks, sliding gates, porous plugs for steel ladles, furniture for ceramic kilns, filters in metal production, and others. white tabular alumina is a recrystallized sintered high density alpha alumina. It is composed of large (50-200 µm), flat shaped Alumina corundum crystals (tabular corundum).

  • Abrasive Industry
  • Ceramic Industry
  • Refractory Industry

In some of these applications, white tabular alumina (Alumina corundum) displaces fused alumina and white fused alumina because of its low porosity, thermal shock endurance, mechanical strength, anti-corrosive properties, and chemical inertness.

  • High corrosion resistance
  • High thermal shock stability,
  • Low porosity
  • High mechanical strength
  • Chemically inert
  • High density

Tabular corundum can be used as the main component of aluminum carbon, aluminum magnesia carbon, magnesia aluminum carbon, magnesia spinel, aluminum chromium refractory bricks, and can also be used as a component to introduce high alumina refractory bricks to enrich alumina. Special-shaped refractories can be widely used in steel, casting, ceramics and other industries. The application in the steel industry covers almost the entire process of ironmaking and steelmaking.
