Abstract

See full text

A piezoelectric glass ceramic represented by the formula

description='In-line Formulae' end='lead'(M1Ox)-(M2Oy)—SiO2 description='In-line Formulae' end='tail'

wherein M1 is one or more metals and/or metalloids, M2 is one or more metals and/or metalloids, x is a value equal to the valence of M1, and y is a value equal to the valence of M2. The piezoelectric glass ceramic has a total alkali metal concentration of less than about 1000 parts per million by weight (ppmw). A process of preparing a piezoelectric glass ceramic and a piezoelectric glass ceramic body prepared therefrom.
