Quartz glass tube, also known as quartz tube, is a kind of glass tube made of high purity quartz sand (the main component is silicon dioxide SiO2) as raw material, which is melted at high temperature through a special process. It has the following six characteristics:

1. High temperature resistance: quartz glass tube softening point of about 1730 ℃, can be used for a long time in the high temperature environment of more than 1000 ℃ without deformation, suitable for use as a high-temperature environment of the experimental equipment or industrial materials.

2. Excellent transmittance: quartz glass tube in the visible and ultraviolet light range of transmittance is very high, especially suitable for use as optical instruments in the lens, prisms and other components.

3. Chemical stability: quartz glass tube has good chemical stability, in addition to hydrofluoric acid and phosphoric acid, almost no reaction with other acids, in most chemical reagents are very stable.

4. Electrical insulation: quartz glass tube is a good electrical insulation material, especially at high temperatures still maintain good electrical insulation properties.

5. Low coefficient of thermal expansion: The coefficient of thermal expansion of quartz glass tube is very low, about 5.0×10^-7/°C, which makes it able to maintain the stability of shape and size when the temperature changes, and is not easy to break due to the temperature difference.

6. High Mechanical Strength: Although quartz glass has a low hardness, it has a high compressive strength and a certain degree of impact resistance, and exhibits good mechanical strength in many industrial applications.

Due to these characteristics, quartz glass tube is widely used in semiconductor, lighting, laboratory instruments, chemical and nuclear industries.
