Quartz tube is one of the special industrial material which is made of SiO2. It is a very good material base.
Quartz tubes can be used for infrared quartz heater, tube heater etc.
Quartz tube has many excellent physical and chemical properties.
Corrosion resistance: quartz tube is resistant to any acid except HF acid. The ability of corrosion resistance is 30 times more than the ceramic, and 150 times more than stainless steel, especially chemical stability at high temperature, any other material engineering can not compare.
Quartz tube heat resistance: quartz melting temperature is 1730 ℃; can be used in the temperature 1200 ℃ for a long time, the maximum short-term temperature reaches 1450 ℃.
Quartz thermal conductivity：Low coefficient of thermal expansion (5.5x10-7 / ° C, the quartz tube can be increased to a Centigrade temperature, then put it in water at normal temperature, the tube will not crack).
Quartz optical properties：The quartz tube has good light transmittance properties in the entire spectral from ultraviolet to the infrared. the visible light transmittance is 98% or more, especially in the UV spectral region, the maximum transmission rate can be up to 90%.
Due to the excellent physical and chemical properties, quartz tube is widely used in electricity, semiconductors, optical communications, military industry, metallurgy, building materials, chemicals, machinery, electricity, environmental protection and other fields.
We supply kinds of quartz tube of different colors, white or milky, transparent, pink, blue, black, yellow. The surface is smooth. We have supplied the quartz tube in Colombia, Brazil, Mexico, etc.
