quartz rod, quartz glass rod, quartz rod manufacturer, quartz rod priceˎ ̥ quartz glass rod company have the specifications for diameter of 1.38 mm and 1.4 mm and 1.5 mm, 1.8, 1.9, 2.0, 3, 4, 5, 6, 10 mm, 20, 25, 28, 30, 50 and specifications of the quartz rod. Product use: used in single end halogen lamp pressure bridge bar, fiber optic lighting, quartz fiber manufacturing, semiconductor silicon wafer processing, etc. This clear quartz rod has high purity, high temperature resistance and thermal expansion coefficient is low characteristic, used in single end halogen lamp pressure bridge bar, fiber optic lighting, quartz fiber manufacturing and semiconductor silicon wafer processing, etc. Quartz glass features: 1. The high temperature resistant, quartz glass softening point temperature of about 1730 degrees, 1100 degrees in the long time use, short time maximum working temperature can reach 1450 degrees. And the glass softening point is about 700 degrees. 2. Corrosion resistance. Except hydrofluoric acid outside, quartz glass was almost not with other acids material produces chemical reaction, this benefits from quartz glass is pure atomic crystal - made of silicon dioxide, the acid ability is ceramic 30 times, stainless steel 150 times, especially in high temperature chemical stability, is any other engineering material can match. 3. Good thermal stability. Quartz glass of coefficient of thermal expansion is tiny, can withstand the severe temperature changes, the quartz glass heated to a temperature of about 1100 degree, put cold water will not burst. 4. Pervious to light performance good. Quartz glass in the ultraviolet to infrared whole spectrum band have good pervious to light performance, visible light transmittance over 93%, especially in ultraviolet spectral region, the biggest through rate can amount to 80% above. 5. Electrical insulating performance is good. Quartz glass resistance value is equivalent to ordinary glass ten thousand times, is an excellent electrical insulation, even in high temperature also has a good performance
