Abstract: Small particle size of zirconium hydroxide was synthesised by ammonia drum , the chemical structure of the Zr(OH) 4 were charactered by FTIR, the particle size of zirconium hydroxide was tested by a Dynamic light scattering.The effects of zirconium ion concentration, reaction time, reaction temperature, stirring speed, aging time and the seed crystal method on hydrogen zirconium oxide particle size were investigated.The results showed that the optimum conditions for the preparation of ammonia drum zirconium hydroxide by Global: the concentration of zirconium ion was 1 mol /L, the reaction temperature was 60 ℃, the reaction time was 4 h, the stirring speed was 1200-1400 r/min, aging time was 1 h, the addition of sodium hydroxide was 10％ of the amount of ammonia required for the reaction in the seed crystal method.
