Molecular formula : MW : CAS :
nature : from the silica glass composition. The opaque and transparent two. Opaque to pure quartz sand as raw material, resistance furnace for melting, which contains large amounts of refined bubbles. Transparent to the special high silica content in the crystal as raw material, high-frequency vacuum melting furnace. In addition to the pure crystal of raw materials, dusting hydroxide flame, made available optical quartz glass. Quartz glass can have a lot of advantages, such as Ta Mok's seven hardness, low expansion coefficient and high temperatures, heat shock, chemical stability and electric insulation is good, with the exception of hydrofluoric acid and heat resistance can be phosphorylated other outside acid erosion. A transparent quartz glass a good performance through ultraviolet. Used in the manufacture of high-temperature corrosion resistance of the chemical equipment, optical equipment, electrical equipment and medical equipment.
