Effect of Ph and Concentration on the Synthesis of Monodispersed Spherical Fine Zirconia Powders Using Gas-Liquid Phase Reaction

摘要

Ammonia gas was blown into the solution of zirconium ion to induce homogeneous precipitation of supersaturated zirconium ion at gas-liquid interface with increase in pH. The precipitates formed using interface of gas-liquid phase were decomposed into fine spherical zirconia powder of high purity. As Concentration increase, mean diameter of particles increases to 140, 180, 240, 290 and 630nm. At pH of 4.5, maximum yield of 98.7
