Lithium niobate crystal, referred to as LN, belongs to the trigonal crystal system, distorted perovskite type structure. The distorted LiNbO3 crystal has many properties, such as piezoelectric, ferroelectric, photoelectric, nonlinear optical, thermoelectric and so on. The piezoelectric coefficients of LN crystal reach high values of 6–70 pC/N, on the orientation. The effective piezoelectric d22  of LiNbO3 is nearly 10 times the magnitude of α-quartz (SiO2) (2–3 pC/N) . 
Further more, the competitiveness of LiNbO3 is also reflected by the high electromechanical coupling factors. By data illustration, the thickness extensional (TE) electromechanical coupling factors kt for the Z- and Y/35°crystal cuts are nearly 17% and 49%, respectively. The electromechanical coupling factors of thickness shear (TS) mode of the X-cut reach a 68% potential for the piezoelectric transducer applications.
Hangzhou Shalom EO offers the SAW grade lithium niobate (or LiNbO3) crystals and wafers, advanced facilities are equipped for crystals growing, wafer cutting, wafer lapping, wafer polishing and wafer checking, all finished products are passed at Testing of curie Temp and QC inspections.  The SAW grade or acoustical grade LiNbO3 crystals boules or ingots, blanks, wafer blanks and polished wafers are available upon customer's request.
