Quartz tube and glass tube difference lies in: quartz tube material is mainly silicon dioxide, hardness and transparency is higher than glass tube; And the quartz tube is resistant to high temperature, wear and tear, and has stronger oxygen resistance. The composition of glass tube is sodium silicate, silicon dioxide and calcium silicate, mainly with sodium silicate, his hardness, transparency, high temperature resistance, wear resistance to want a lot of difference. Quartz glass tube is a kind of special industrial glass made of silica, which is an excellent basic material. Quartz glass has a series of excellent physical and chemical properties. Used in electric fire barrel, electric oven, electric heater, heating effect.
