Product Description
Quartz glass rod with a diameter of 1.38mm, 1.4mm, 1.5mm, 1.8,1.9,2.0,3,4,5,6,10 mm, 20,25,28,30,50 and other specifications of the quartz rod. Usage: bridging rod for single-ended halogen lamps, fiber optic lighting, quartz fiber manufacturing, semiconductor wafer processing. This transparent quartz rod has high purity, temperature resistance and low coefficient of thermal expansion for the single-ended halogen bridging rod, fiber optic lighting, quartz fiber manufacturing semiconductor wafers processing. The characteristics of the quartz glass: 1. High temperature, the softening point temperature of the quartz glass is approximately 1730 degrees for prolonged use at 1100 degrees the short maximum use temperature of up to 1450 degrees. Glass softening point of about 700 degrees. Corrosion. Except hydrofluoric acid, the quartz glass is almost no chemical reaction occurs with the other acids, which thanks to the quartz glass is pure atomic crystal - made of silica, and its acid capacity is 30 times that of the ceramic, stainless steel 150 times, especially in the chemical stability under high temperature, is unmatched by any other engineering materials. 3 good thermal stability. A very small coefficient of thermal expansion of the quartz glass, and be able to withstand severe temperature changes, the quartz glass is heated to about 1100 degrees, into the water at room temperature and will not burst. 4 good light. Have better light transmission properties of the entire spectral band of the quartz glass in the ultraviolet to the infrared, visible light transmittance at 93% or more, particularly in the UV spectral region, the maximum transmittance of up to 80% or more. 5 good electrical insulation properties. Equivalent to one million times that of ordinary glass, the resistance value of the quartz glass is an excellent electrical insulating material also has good electrical properties, even at high temperatures
