Nd2Ti2O7 (NTO) with high curie temperature (TC) for high temperature sensor applications

High curie temperature ternary piezoelectric ceramics

A preferred piezoelectric ceramic material is a BiFeO3—PbZrO3—PbTiO3 ternary solid solution wherein proportions of the constituent perovskite metal oxides are selected so that the material exhibits relatively high Curie temperatures above 380° C. and useful piezoelectric properties.

High Curie temperature BiInO3-PbTiO3 films.

High Curie temperaturepiezoelectricthin films of xBiInO3-(1-x)PbTiO3 (x = 0.10, 0.15, 0.20, and 0.25) were prepared by pulsed laser deposition. It was found that the tetragonality of films decreased with increasing BI content. The dielectric constant and transverse piezoelectric coefficient (e31,f ) exhibit the highest values of 665 and -13.6 C/m2 at x = 0.20. Rayleigh analyses were performed t...

Langasite Bulk Acoustic Wave Resonant Sensor for High Temperature Applications

The high temperature transport properties of langasite, La3Ga5SiO14, were investigated with special attention focused on their potential impact on the utilization of langasite as a mass sensitive resonant platform for high temperature sensor applications. The electrical properties of acceptor and donor doped langasite were examined at temperatures ranging from 700 to 1000C, and pO2 of 1 to 10at...
