5mm x 5mm x 45mm LGS Single Crystal With Electrodes Bar

Lanthanum gallium silicate ( La₂Ga₅SiO₁₄ ) is a phenomenal invention. Though langasite was initially developed as a laser crystal, it revealed a remarkable combination of piezoelectric qualities, which opened up new opportunities to use the LGS crystal in radio frequency devices. The main applications of langasite crystals now is SAW filters and SAW resonators. Experts agree that LGS is the best choice for high-efficiency broad band frequency devices because it possesses exceptional frequency-temperature characteristics, a very high index of electromechanical coupling and unparalleled Q-factor.
Langasite crystal (La3Ga5SiO14,LGS), belonging to the space group P321, point group 32, has been reported to be promising new piezoelectric materials for fabrication of surface acoustic wave (SAW) and bulk acoustic wave (BAW) devices. The devices made of langasite crystal could be used at a high temperature up to 900℃ because of its high thermal stability.
