Product Details

The pore volume of our macroporous pseudoboehmite is 0.9-1.2ml/g. There are high silicon macroporous pseudoboehmite and low silicon macroporous pseudoboehmite.


Macro pore volume pseudoboehmite is also called aluminum hydroxide dry glue or macroporous pseudoboehmite, a hydrate alumina, false monohydrate soft diaspore. It can used in different application according to the different production process .We use high purity aluminium hydroxide and ionic membrane alkali as raw materials, after the carbonation to produce series of macroporous pseudo boehmite( macroporous pseduboehmite) with different process


It can be used as a binder for semi-synthetic rare earth Y zeolite cracking catalysts, binders for aluminum silicate refractory fibers, ethylene dehydration catalysts and ethylene oxide catalysts, etc. It can also be used as catalyst carrier, activated alumina and others. Aluminum salt raw materials.

The product γ-Al2O3 calcined at 400-700°C is widely used as a catalyst carrier, catalyst and adsorbent, etc.; it is calcined between 1100 and 1200°C to obtain nanometer α-Al2O3, widely used as coating additive, high-grade ceramic, High-efficiency catalysts for petrochemical industry, submicron/nano abrasive materials and polishing materials, cosmetic fillers and inorganic film materials are a class of new materials with broad development prospects.
