Crystal Quartz has trigonal crystal structure with right-handed or left-handed modification. Quartz crystals have low stress
Introduction:
Single Synthetic Crystal Quartz is grown by hydrothermal method in autoclaves. It has trigonal crystal structure with right-handed or left-handed modification. Quartz crystals have low stress birefringence and high refractive index homogeneity. The optical transmission range of crystal quartz is 0.15-4 microns. Due to its piezoelectric properties, low thermal expansion, good mechanical parameters and excellent optical characteristics, cultured quartz is used in electronics, precision and laser optics, optical fibre communications, X-ray optics, and pressure sensors, ect..
Quartz crystal of this grade is used for applications that need excellent optical characteristics and large size ingot to produce optical filters, windows, prisms etc.. Usually it is specified by inclusion and homogeneity. This material is mostly grown along the C-axis. Quartz crystals with inclusion specifications of Ia and Ib grade(IEC) is available in ATOM.
