Synthetic quartz crystals are analogous to the natural ones. Synthetic crystals have high reliability and stability of parameters. Quartz crystals have the wide range of application: from piezoelectric engineering and acoustic electronics to the optical units. Crystals have the right enantiomorphic modification and no twins. Orientation accuracy is 15'. There are the following main grades: ZY, ZX, XZ, XY, Z to direction of the growth face.
