Product Description High temperature resistance Quartz glass softening temperature of about 1730 ℃, prolonged use at 1100 ℃, short-term maximum temperature up to 1450 ℃ Corrosion resistance In addition to hydrofluoric acid, the quartz glass hardly occurs acids with other chemical reactions, its acid capacity is 30 times than ceramic, 150 times than stainless steel , especially in chemical stability at high temperatures, any other engineering materials are unable to match with Good thermal stability Coefficient of thermal expansion of quartz glass is extremely small, can withstand severe temperature changes, the quartz glass is heated to about 1100 ℃, placed in water at room temperature will not burst Good light transmission Quartz glass in the ultraviolet to infrared spectral bands throughout have good light transmission properties, visible light transmittance of 93% or more, particularly in the UV spectral region, the maximum transmittance of 80 or more Good electrical insulation properties The resistance value of the quartz glass is corresponds to ordinary glass ten thousand times, is an excellent electrically insulating material, even at high temperatures also have good electrical properties. Quartz glass has the above excellent physical and chemical properties, so it is widely used in emiconductors, optical communications, military, metallurgy, chemical, mechanical,and other fields Technical Datas Model name :Quartz Beaker Capacity:300ml
