A quartz tube is a type of tube made from high-purity quartz material, typically with a cylindrical shape. Quartz tubes are known for their high temperature resistance, low thermal expansion, and excellent optical transparency. They are commonly used in a variety of industrial and scientific applications, such as semiconductor manufacturing, chemical processing, and research in materials science.

In semiconductor manufacturing, quartz tubes are often used in furnaces for processes such as chemical vapor deposition (CVD) and thermal oxidation. The high purity of quartz material helps to prevent contamination of the semiconductor materials being processed.

In chemical processing, quartz tubes are used in high-temperature and high-pressure reactions, as well as in analytical instrumentation such as spectrometers.

In materials science research, quartz tubes are used in experiments that require high-temperature heating, such as synthesis of new materials or characterization of materials under extreme conditions.

Quartz tubes come in various sizes and shapes, depending on the specific application requirements. They are typically made by melting high-purity quartz material and drawing it into a cylindrical shape, followed by cutting and polishing to achieve the desired dimensions and surface finish.
