Tabular aluminas grit is made of Al2O3, after ingredients, grinding and forming, smelting in high temperature furnace turned to α- Al2O3.
Tabular aluminas grit has good heat resistance and good bulk temperature thermal shock capabilities. Tabular alumina 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.

Henan sicheng Abrasives Co.,ltd. was established in 2009. It covers the area of 10 years. With updated new equipments, our factory can produce tabular alumina 150,000 tons per year. It is one of the high grade refractory grains production base in China.
We have our own individual laboratory, the testing method for particle size is laser measuring method. From raw material choosing and purchasing, production processes, to market & sales, we all have very high standards. which makes our products very popular among Japan, Korea, Southeast Asia, Middle east and European countries.
