LEAD-FREE PIEZOCERAMIC MATERIAL BASED ON BISMUTH SODIUM TITANATE (BST)
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<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.
