摘要
Abstract
Hydroxyapatite was prepared by co precipitation method.PVA,anhydrous ethanol and citric acid were used as dispersing agents to compare the dispersion effects of three dispersants and to explore the optimum parameters for the preparation of hydroxyapatite.The experimental results show that the use of 0.2 mol/L Ca(NO3 )2 solution as raw materials and 0.5 mol/L ethanol as dispersant for preparation of HAP powder particle size minimum;after 1100 ℃ strength of ce-ramic samples after sintering best;adding glass powder can increase the strength of ceramics,and glass powder content in-creased with increased intensity of glass powder is added;in HAP powder,ceramic shrinkage,density becomes smaller, and can improve the ceramic porosity and acid resistance,the porosity rate and acid resistant ceramic ashes best.关键词
