Method of making porous inorganic bodies using water-soluble zirconium compounds

摘要

Disclosed are methods of making porous bodies of SiO2, Al2O3, and TiO2 having average pore diameters which closely approximate the particle size of the starting material used to form the porous bodies, thereby permitting the production of porous bodies having a very uniform pore size distribution such that the diameters of about 90 percent of the pores are within +/-20 percent of the average pore size of the material. The process involves forming a uniform slurry of metal oxide particles of SiO2, Al2O3, or TiO2 having substantially uniform particle size and a liquid binder consisting of a solution containing a water soluble zirconium compound, gently drying the slurry, and firing the mixture at a temperature below that at which the material sinters.
