It has large pore volume, large specific surface area and good water absorption. The radial purity is high, the moldability is good, and it has the characteristics of a thixotropic gel. The product has good dispersibility, is easily soluble in strong acid and strong alkali solutions, and has good molding properties. After being roasted and dehydrated at low temperature, it becomes highly active alumina.
