Transparent quartz rods are made of high purity crystal flour . It was pulled out from high temperature melting furnace. Using world advanced technology and equipment, after testing and improving, the outer surface and inner quality of the products meet international standard.  The surface is smooth and the tube is colorless, SiO2>99.99%. The properties of the rods are: high purity; abrasion resistance(except hydrofluoric acid & hot phasphoric acid ); fire resistance(softening point 1650 centigrade); low coefficient of thermal expansion(5.5x10-7/centigrade), excellent electrical property. It is widely used in electronics, semiconductor, optical fiber field and so on.
