以(NH_4)_2HPO_4和Ca(NO_3)_2·4H_2O为基本原料,加入一定量的聚乙二醇作为分散剂,采用液相沉淀法制备磷酸钙盐前驱体,经过850 ℃高温煅烧制得结晶度较高的β-磷酸三钙(β-TCP)粉体.采用XRD、TEM和粒度分析等手段对粉体进行测试,分别研究了pH值、分散剂聚乙二醇(PEG)的分子量及加入量对产物物相组成、团聚程度的影响.结果表明,控制pH值为7～8,加入1.5%的PEG6000作为分散剂,可制得纯度高、结晶状态良好、分散性好的β-TCP粉体.

Calcium phosphate was synthesized by precipitation methods with (NH_4)_2HPO_4 and Ca(NO_3)_2·4H_2O , Polyethylene glycol(PEG) was used as dispersant. The β-TCP powders was obtained after calcined at 850 ℃. The heat-treated powders were analyzed by X-ray diffraction (XRD), transmission electron microscopy (TEM) and particle size analysis. The influence of pH value and the molecular weight of PEG on the phase composition, agglomeration were investigated. It was found that the β-tricalcium phosphate powders with high purity, fine crystalline and steady dispersivity could be synthesized when the pH value is 7-8 and the molecular weight of PEG is 6000.
