Lead-free piezoceramic material based on bismuth sodium titanate (BNT)

HENNIG EBERHARD / KYNAST ANTJE / TOPFER MICHAEL / HOFFMANN MICHAEL

The invention relates to a lead-free piezoceramic material based on bismuth sodium titanate (BST) having the following parent composition: x(Bi0.5Na0.5)TiO3-yBaTiO3-zSrTiO3 where x+y+z = 1 and 0<=z<=0.07 or x(Bi0.5Na0.5)TiO3-yBaTiO3-zCaTiO3 where x+y+z = 1 and 0<=z<1, characterized by addition of a phosphorus-containing material in a quantity that gives a phosphorus concentration of from 100 to 2000 ppm in the piezoceramic material.

本发明涉及基于钛酸铋钠(BNT)并且具有以下基本组成的不含铅的压电陶瓷材料：x(Bi0.5Na0.5)TiO3‑yBaTiO3‑zSrTiO3，其中x+y+z＝1，并且0<1，其特征在于，加入一定量的含磷材料，使得压电陶瓷材料中的磷浓度为100至2000ppm。
