| 摘 要： | 介绍了功率型压电陶瓷振子的研制过程。采用二次水磨加黏合剂造粒方法，并使用超细ＺｒＯ２，使烧结温度降低，从而减少ＰｂＯ的挥发。作者对铌锂锆钛酸铅系统做了大量的配方筛选工作，确定了性能满足使用要求的配方（Ｐｂ１－ａＳｒａ（Ｌｉ１／４Ｎｂ３／４）０．１２Ｚｒ０．４６Ｔｉ０．４２Ｏ３）。叙述了功率型压电陶瓷振子在超声清洗、超声焊接、超声钻孔等方面的应用。

| Abstract: | The development and applications of the said vibrator is presented With the process of double wet grinding granulating and superfine ZrO 2 powder, the sintering temperature is reduced and the volatilization of PbO is limited Through the experiment with Pb(Li 1/4 Nb 3/4 )O 3 PZT, a practical formular is decided, that is, Pb 1 a Sr a(Li 1/4 Nb 3/4 ) 0 12 Zr 0 46 Ti 0 42 O 3 The applications of the vibrator in cleaning, welding and drilling are also presented (4 refs ) |
