3X3X20mm AR 1064nm Piezoelectric Materials La3Ga5SiO14 single
crystal (LGS)
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.
a.Crystro's LGS crystal has High thermal stability,low equivalent
series resistance ratio and electro-mechanical coupling coefficient
is 3-4 times than quartz.
