Product Details
Synthetic quartz single crystal is grown by hydrothermal method in Autoclave, and has two forms: left hand and right hand. Quartz crystal has low stress birefringence and high refractive index uniformity, with a transmittance range of 0.15-4 μ M. Quartz crystal has been used in electronics, precision optics, laser technology, optical communication and X-ray optics due to its piezoelectric properties, low thermal expansion coefficient, excellent mechanical and optical properties.
Quartz crystals have important application value in industrial and technological fields. In the structure of quartz, silicon and oxygen form tetrahedral units, which are linked together by sharing oxygen atoms, forming a unique crystal structure of quartz. This structure endows quartz with many unique physical and chemical properties. Synthetic quartz single crystal is grown by hydrothermal method in Autoclave, and has two forms: left hand and right hand.
Quartz crystal has excellent mechanical and electronic properties, including hardness, chemical stability, thermal stability and excellent Piezoelectricity. Among them, the Piezoelectricity is one of the most remarkable properties of quartz, that is, under the action of mechanical pressure, quartz crystal can produce electric charges.
Because of its excellent Piezoelectricity, quartz crystal is widely used in various electronic devices, such as oscillators, filters, timers, etc. These devices utilize quartz crystals to generate stable frequency oscillations under voltage excitation, in order to achieve precise frequency control. In addition, quartz crystals are also used in sonar equipment, piezoelectric heaters, and optical applications such as lenses and prisms.
