4mm x 4mm x 50mm LGS Single Crystal With Au Coating Bar
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.
Crystro's LGS wafer is grown by Czochralski method.Max diameter reach 60mm.Crytsro can custom size and cutting
direction accordding to customer's needs,Our standard size
including LGS Crystal bar: 3x3x20mm,4x4x50mm,5x5x45mm... LGS
Crystal wafer: D2inchx0.5mm,D50x0.5mm,40x40x0.5mm...Piezoelectric
crystal including LGS,LN,LT,BBO,DKDP are CRYSTRO's main prodcuts..
