Activated Alumina Powder for The Production of Adsorbents Catalysts Carriers Desiccant Sulfur

Activated Alumina Powder for The Production of Adsorbents Catalysts Carriers Desiccant Sulfur

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 have a good reputation in the domestic and international markets for the performance of our Detergent Zeolite, ultra fine aluminium hydroxide, alumina trihydrate ath and the quality of our services. We will provide one-to-one service and provide perfect and reasonable product quotation to ensure the best interests of customers. We always insist on serving customers with the user first, and stick to using our own services to impress customers.

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.
