Boehmite
Boehmite is an important precursor for the preparation of y- Al₂O₃, and a- Al₂O₃, Mainly used in catalystand its carrier materials, coating material, porous membranes and soft abrasive, high temperature ceramicsetc.
Application of boehmite in fre-rotardant and insulation material
This product i widoly used in the catalyst arrters, fire retardants, insulation materals, oloctronic C0-ramic substrales and other industries. which is good taw material of Catalyst carmiers, stablzers. cloringagents and other products
