Quartz plate
I plant the production of Chang Da quartz plate, made of quartz smelting and cutting grinding together, the silica content can reach more than 99.99%. Hardness is seven, with high temperatures, low coefficient of thermal expansion, thermal shock resistance and electrical insulation properties and other characteristics of a good. Usually colorless transparent, visible light transmittance of more than 85%.Quartz plate has its one's own knack in optical properties, it can be through the far ultraviolet, ultraviolet permeable materials are all the best, but also through the visible to near-infrared spectroscopy. As the quartz glass high temperature, thermal expansion coefficient is small, good chemical stability, bubble, stripes, uniformity, birefringence can be comparable with general optical glass, so it is in the work under various bad situations is of high stability optical coefficient of essential optical materials.
