Abstract:Various preparation techniques and the corresponding produc tor properties of nanostructural zirconia particles prepared by precipita tion method in and out of abroad were summarized. Many effects of zi rconium salt concentration, the concentration and speciese of doping reagent (Y³⁺、Mg²⁺、Ca²⁺、Ce⁴⁺ et al), pH value, disposal of precipitation and heat treatment, etc on the character of production were introduced and analyzed in detail. And the mechanisms of those effects were sum marized respectively. The hotspot and emphases in this field based on the tendency in the material science and market request was also point ed out .
