Piezoelectric glass ceramic compositions and piezoelectric devices made therefrom |
摘要 |
A piezoelectric glass ceramic represented by the formula
(M1Ox)-(M2Oy)—SiO2
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. |

1. A piezoelectric glass ceramic represented by the formula
(M1Ox)-(M2O)—SiO2 wherein M1 and M2 are independently 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; wherein said piezoelectric glass ceramic has a total alkali metal concentration of less than about 1000 parts per million by weight (ppmw); and wherein the piezoelectric glass ceramic is non-ferroelectric. |
