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..
