Product Name: High Purity and Good Appearance Quartz Glass Sheet Model NO.: YKW-028 Size: 1-40mm Application: Mechanical Components Type: Quartz Type: Clear Quartz Plate: Shape: Circular Shape Place of Origin: Jiangsu, China (Mainlan: Purity: 99.99% Min Softening Point: 1683 Degree: Annealing Point: 1215 Degree Density: 2.2g/cm3: Defoamation Point: 1120 Trademark: YuKang Transport Package: Outside Wooden Cases, Inside Carton Case with Foam Origin: Donghai County of Jiangsu Province Product Description SpecificationsQuartz disc 85%Transmission min1, quartz disc 85%Transmission min2, Broad Transmission Spectrum3, Resistance 1100 degree4, no bubble no airline5, ISO 9001In semiconductor and photovoltaic (PV) industry, the whole range of quartz glassComponents are used for the fabrication of quartz washing tanks and quartz boats forWafer cleaning and many other applications with a working temperature up to 800 degree. DuTo the elevated sodium (Na), quartz plate cannot be used for high temperature applicatioWith a steady temperature up to 1100 degree. The sodium will cause glass devitrification. WeAre pleased to offer you a sample of the material to test the suitability of the material forYour individual application. In lightingBecause of its high purity, EN08 has an excellent transmission in the UVC range of 200-280nm wavelength. By vacuum annealing, the OH content of plate can be lowered to 20-30ppm. Quartz plate is a good material for UVC disinfection. Also quartz plates are used in other UV applications such as cover plates for UV curingSystems and lower optical applications. Fabrication of the plates< 5mm: Manufactured from tubes> 5mm: Manufactured from block material/ingotsPhysical PropertiesDensity 20oC g/cm3 2.2Softening point(oC) 1683Annealing point(oC) 1215Defoamation Point (oC) 1120Application: Widely used in Medical, Electronics instrument, Scientific research, Optical industry etc
