Abstract: The methods for producing inorganic particles with a narrow particle size distribution, which are useful as chromatographic packing materials for high performance liquid chromatography(HPLC), are provided.These methods are based on improvements in the polymerization induced colloid aggregation(PICA) process described.These improved methods involved both synthesis of zirconium oxide colloid and sintering method.Colloid is an important factor in the PICAprocess.The reaction factors of the aqueous sol colloid of zirconium oxide are studied.We use sintering procedure to sinter zirconium oxide colloid, the average particle size is 5μm.Owing to different sintering procdure, the average pore size is between7.0_32 nm and the average surface area is between44_87 m2/g

Key words: Zirconia, Colloid, Packing, PICA
