Description for tabular alumina:
Tabular alumina has good heat resistance and good volumetric temperature shock ability. Crystal shape plate 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 reused fluids; With good physical properties such as: high refractory, excellent thermal shock resistance, low shrinkage and good strength under thermal load, etc. Meanwhile, high cleanliness preventing damage to machines. Hiaxu abrasives is your best choice as refractory material/ceramic material and insulation materials.
