white colour sintered tabular alumina powder 200#-0 -200mesh

Production: tabular corundum for cast-ing chemical index:  Al2O3: 99.3%min SiO2: 0.1%max Fe2O3:0.08%max Na2O: 0.4%max   physical index: Volume density: 3.5g/cm3 water absorption: 1.5 apparent porosity: 5max

Tabular corundum has good heat resistance and good bulk temperature thermal shock capabilities. The crystal staggered plate shape, to increasing the mechanical strength of the particles; interior structure full of closed pores, high bulk density, low apparent porosity and water absorption, to reducing the amount of fluid re-use productions; With good physical properties like: high refractoriness, excellent thermal shock resistance, low shrinkage and good thermal load strength etc. Meanwhile, high-purity avoiding damage to machines. Hiaxu/Sicheng is your best choose as refractory material/ceramic material and insulating materials.
