Refractory Material Tabular Alumina with 3.5% Bulk Density

Refractory Material Tabular Alumina with 3.5% Bulk Density

Tabular alumina is a kind of pure sintered corundum without adding any additives such as MgO, B2O3 and so on, with low shrinkage.

Description

Market competition is a race without end, and we are actively developing new 4a zeolite for detergent, calcined metallurgical grade alumina, Alpha High Purity Alumina and increasing new varieties. Under the background of the new era, we inject new development opportunities for products through new marketing, operations, and market environments. We improve our internal management and continue to respond to customer expectations.

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.
