【摘要】 本文研究了锰掺杂对ＰＺＮ－ＰＦＮ－ＰＦＷ系陶瓷相组成的影响，用ＸＲＤ和ＳＥＭ法探讨了ＰＺＮ－ＰＦＮ－ＰＦＷ系中ＰＺＮ含量与焦录石相形成间的关系。结果表明，在该三元系中添加０．１５ｗｔ％ＭｎＣＯ＿３就能获得完全无焦录石的钙钛矿型结构的陶瓷。更多还原

【Abstract】 The effect of Mn-dopd on theComposition of PZN-PFN-PFW system ceramics wasstudied.The relationship between the amount ofPZN and the formation of pyrochlore phase in PZN-PFN-PFW system was studied by using XRD andSEM methods.The results show that completeperovskite type structure without pyrochlore could beobtained by adding 0.15wt%MnCO₃ in this ternary system.更多还原
