Product Description
Introduction :
The lanthanum gallium silicate (La3Ga5SiO14, LGS) piezoelectric crystal belongs to the trigonal crystal system, 32 point group, P321 space group, and has been a hot spot in the field of piezoelectric crystal research for the past two decades. This crystal has 2 to 3 times the electromechanical properties of quartz. Coupling coefficient, good temperature stability, and excellent piezoelectric properties, especially high-temperature piezoelectric properties. Due to its excellent piezoelectric properties, it can be used to make all kinds of piezoelectric devices.
Main Advantages :
- The electromechanical coupling coefficient is (3-4 times of quartz)
- High thermal stability
- The low equivalent series resistance ratio
