Refractory castable material 0-1mm 1-0mm tabular alumina grit

Tabular alumina grit is alpha-alumina with sheet-shaped crystals, aluminum oxide feedstock is calcined alumina ground to a fine powder and palletized to balls with an abt diameter of 25 mm. These balls are sintered (fired) at 1750°C in modern shaft kilns and following crushed, milled, and sieved to standard fractions/sizes. tabular alumina grit is a re-crystalline sintered alpha alumina with high density. It consists of large (50 – 200 µm), flat, tablet-shaped corundum crystals.

Refractory castable material 0-1mm 1-0mm tabular alumina grit

Description for tabular alumina grit:

Tabular alumina has good heat resistance and good thermal shock capabilities at bulk temperature. Crystal stepped plate shape to increase the mechanical strength of the particles; internal structure full of closed pores, high bulk density, low apparent porosity and water absorption to reduce the amount of fluid reuse production; With good physical properties such as: high heat resistance, excellent thermal shock resistance, low shrinkage and good thermal load strength, etc. Meanwhile, high purity prevents machinery damage. Hiaxu abrasives is your best choice as refractory/ceramic material and insulation materials.
