Pseudo-boehmite: also known as monohydrated alumina, pseudo-monohydrate soft boehmite. Its series include: pure aluminum hydroxide powder, silicon-aluminum composite aluminum hydroxide powder, silica-aluminum colloid, active magnesium aluminum spinel precursor, alumina special-shaped carrier series, macroporous pseudo-boehmite, low sodium pseudo-boehmite.
This product is odorless, the wet product is white colloid, the dry product is white powder, the pore size distribution is uniform, the volume is large, and the water absorption is good. The radial purity is high, the molding performance is good, and it has the characteristics of thixotropic gel. This product has good dispersibility, is easily soluble in strong acid and strong alkali solutions, has good molding performance, and becomes highly active alumina after low-temperature roasting and dehydration.
