特殊功能粉体的机械化学合成

摘要

With Calcium phosphate primary and cacium hydride as the raw materials,study on synthesizing β-TCP ceramic powder by mechano-chemicl method was made.β-TCP bioceramic powder with an average particle size of 3.09 μm was synthesized by the mechano-chemical method of agitation grinding.As a result,the exesting difficult problem of the poor bioceramic performances caused by big-sized β-TCP powder was solved.The mechanisn of the reaction of mechano-chemical Synthesizing is discussed.%以磷酸二氢钙和氢氧化钙为原料，开展了机械化学法合成β-TCP陶瓷粉末的研究，采用搅拌磨机械化学法合成了平均粒径为3.09 μm的生物陶瓷粉末β-TCP，解决了目前由于β-TCP粉末粒径大、导致生物陶瓷性能差的难题。最后探讨了机械化学合成反应的机理。
