Quartz plate of JGS1/2

Quartz glass plate&High temperature and pressure observation window& Milky white quartz plateQuartz glassQuartz glass are resistant against high temperature and pressure, and can be applied mainly in such fields as special light sources, optical instrument, optical electronics, military equipment, metallurgy, semi-conductor, and optical communications. Their experimental temperature is 1200 degrees and softening temperature 1730 degrees. Detailed parameters are given as follows: • JGS1( Extreme UV optical quartz glass) It is a high-purity optical quartz glass made by oxyhydrogen flame melting. Its satisfactory UV light transmission performance surpass all the other glass types in particular in the shortwave UV zone and can achieve a 90% transmission rate at the wavelength of 185nm. Hence it is an ideal choice for applications in the wavelength range of 185-2500nm. • JGS2 (UV optical quartz glass) It is an optical quartz glass made by oxyhydrogen flame melting and is suggested for applications in the wavelength range of 220-2500nm. • JGS3 (Infrared quartz glass) It has a good performance of infrared light transmission with a transmittance of over 85%. It is recommended for applications in the wavelength range of 260-3500nm.Quartz glass characteristicsTable1.Mechanical PropertyReference ValueDensity2.2g/cm3Compressive Strength1100MpaBending Strength67MpaTensile Strength48MpaPoisson's Ratio0.14 0.17Elastic Modulus72000MpaShearing Modulus31000MpaMohs Hardness5.5 6.5Table2.Mechanical PropertyReference ValueDeformation Point1280°CSoftening Point1780°CAnnealing Point1250°CSpecific Heat(20 350°C)670J/kg.°CThermal Conductivity(20°C)1.4W/m.°CRefractive Index1.4585Coefficient of thermal expansion5.5×10-7cm/cm.°CHot work temperature1750 2050°CThe temperature for a short time1300°CThe temperature for a long time1100°CTable3.Electrics PropertyReference ValueResistivity7×107Ω.cmDielectric Strength250 400Kv/cmDielectric Constant3.7 3.9Dielectric absorption coefficient<4×104Dielectric loss coefficient<1×104 Please keep attention on our website for more products and news with photos.
