【摘要】 通过对Ｐｈ（Ｓｎ１／３Ｎｂ２／３）Ａ（Ｌｉ１／４Ｎｂ３／４）ＢＴｉｃＺｒＤＯ３（Ａ＋Ｂ＋Ｃ＋Ｄ＝１）四元系压电陶瓷材料的组分、添加物，取代物的研究，找到了这一四元系压电陶瓷材料的最佳组成，其性能满足了发射型换能器件对压电陶瓷材料的性能要求。更多还原

【Abstract】 In this experimental work, through study for material compositions, additives,substitutes of Pb (Sn1/3Nb2/3 )A (Li1/4Nb3/4 ).Ti.Zr.O3, A + B +C +D = 1, four--component--system piezoelectric ceramics material, finds its optimum compositions. This system has reached the requirement of the emission type transducer for piezoelectric ceramics material.更多还原
