【摘要】 以聚乙二醇(PEG)为分散剂,采用溶胶-凝胶法制备了钙钛矿相的PZT95/5粉体,并通过XRD、TG-DSC、ξ电位等方法对其进行表征。结果表明:PEG分子量和加入量不同时,其分散效果也不同。当PEG分子量为10000、加入量为2%时,即可有效的避免PZT组分偏析,有利于合成单一钙钛矿相的PZT陶瓷。更多还原

【Abstract】 Using PEG as dispersant,prepared anatase phase PZT powder by sol-gel, analyse and token have done by XRD、TG-DSC、ξ-potential,etc.It showed that:When doped quantity and molecular weight of PEG was different,its decentralization was not same.When molecular weight is 10000、doped quantity is 2%,it can avoid PbO to separating out from PZT and propitious to composing pure PZT ceramic.更多还原
