Additional Details
Quartz has become one of today's key strategic raw materials raw materials for the high-tech industry. Silica glass melted out of quartz offers a wide range of exceptional optical, mechanical and thermal properties, which are essential for manufacturing many high-tech products in areas such as Semi-conductor Technologies, High Temperature Lamp Tubing, Telecommunications and Optics. Quartz Application: High quality telescopes and laboratory optical lense; Fiber optical cables; Semiconductors; High intensity lamps; Ultra pure Quartz glass; Synthetic Quartz wafers; Crucibles for the production of Solar Grade Silicon ; Quartz wool for high temperature insulation; Fillers for electronics; Flame control Devices High purity quartz in electronics: The main products from ultra pure quartz glass in lighting industry are quartz tubes. The tubes are used for high-temperature mercury, halogen a and UV lamps, thermocouples, semiconductor products, wave-guide auxiliaries and other quartz with low content of water in the crystal lattice, used in casing and bandages for UV and ozone lamps, medical and chemical equipment and in latest models of semiconductor devices. Tubes from melted quartz of high chemical purity and high heat resistance are perfect furnaces for production of silicon wafers for semiconductor industry. The tubes have a diameter of up to 550 mm with an overall content of impurities less than 25 ppm.
