Single Synthetic Crystal Quartz Product Attributes
Single Synthetic Crystal Quartz SiO2 is grown by hydrothermal method in autoclaves. It is a kind of nonlinear optical materials called a kind of birefringent crystal. 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 0.2-2.5microns. It is mentioned that Very thin Crystal Quartz SiO2 Wafer are available from Coupletech. Due to its piezoelectric properties, low thermal expansion, good mechanical parameters and excellent optical characteristics, crystal quartz is widely used in electronics, precision and laser optics, fiber communications, X-ray optics, pressure sensors and etc. Single crystal quartz wafer is an excellent substrate for microwave filters for wireless communication industries. We can provide high quality quartz wafers for both research and industries production at the lowest price. Quartz crystal is an important electronic material. A quartz chip cut in a certain direction will produce an electric field or charge proportional to the stress when subjected to mechanical stress, a phenomenon known as the positive piezoelectric effect. Conversely, when a quartz wafer is subjected to an electric field, it will generate a strain proportional to the electric field, which is known as the inverse piezoelectric effect. Positive and inverse effects are called piezoelectric effects. Quartz crystal not only has the piezoelectric effect, but also has the fine mechanical characteristic, the electrical characteristic and the temperature characteristic. The resonators, oscillators and filters designed and produced with it have prominent advantages in frequency and frequency selection. Coupletech Co., Ltd also manufactures other kinds of Optical Crystal, for example, Nolinear Optical Crystal, Laser Crystal, Magneto-Optic Crystal, Birefringent Crystals.
