Refractory Grade Reactive Alumina Powder High Purity Factory Direct Supply
Tabular alumina is a kind of pure sintered corundum without adding any additives such as MgO, B2O3 and so on, with low shrinkage.
Description
We are constantly expanding the company's product line and producing excellent quality poly aluminium chloride for drinking water, poly aluminium chloride in paper industry, aluminium hydroxide formula. We unswervingly promote industrial adjustment, resource integration, system change, control reconstruction and system optimization. At the same time, the function and quality of the products are guaranteed. We insist on the high unity of economic and social responsibilities to build a harmonious society.
Tabular alumina is a kind of pure sintered corundum without adding any additives such as MgO, B2O3 and so on, with low shrinkage. It has a sheet crystal structure, small pores and more closed pores. It has high purity, good volume stability, and minimal reburning shrinkage. The resistant materials or castables used for production have good thermal shock stability and flexural strength after high temperature treatment.There are 5-10 /3 -6 /1 -3 /0 -1 /0 -0.045mm and other brands.
