- Abstract
- A high-temperature ferropiezoelectric material (glass ceramic) based on the lithium methaniobate, including MNL, calcium and titanium oxides, and glass of the composition Li2O-B2O3-SiO2, has been developed. A comprehensive study of its electrophysical properties was carried out, including the resistance of the d33 piezomodule to external influences. It is shown that the developed material is characterized by a low relative dielectric constant of the polarized samples and can be used in high frequency (f ~ 60.0 MHz) piezoelectric transducers for various purposes, in particular, devices for non-destructive monitoring of the processes in heat-loaded structures.
