As a kind of special industrial technology glass made of high-purity silica, quartz glass tubes have shown significant advantages in many fields, especially when used as containers, due to their unique physical and chemical properties.

1. Excellent high temperature resistance

A distinguishing feature of quartz glass tubes is its high temperature resistance. Its softening point temperature is about 1730 ° C, which can be used for a long time at 1100 ° C, and the short-term use temperature is as high as 1450 ° C. This high temperature resistance makes quartz glass tubes an ideal container material for working in high temperature environments. For example, in the semiconductor manufacturing process, quartz glass tubes can be used as a container for epitaxy, diffusion, oxidation, etc., to ensure that the process is carried out stably at high temperatures.

2. Excellent corrosion resistance

In addition to high temperature resistance, quartz glass tubes also have excellent corrosion resistance. Except for hydrofluoric acid and hot phosphoric acid, quartz glass hardly reacts chemically with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, and its chemical stability is unmatched by any other engineering material, especially at high temperatures. This property has made quartz glass tubes widely used in the chemical industry, such as in the manufacture of corrosion-resistant pipes, containers, etc.

3. High transparency and good light transmission performance

Quartz glass tubes also perform well in optical properties. They are extremely transparent and can pass through most light, especially in the entire spectral band from ultraviolet to infrared, and their light transmission performance is particularly excellent. The visible light transmittance is over 93%, especially in the ultraviolet spectral region, the transmittance can reach more than 80%. This high transparency makes quartz glass tubes play an important role in the manufacture of optical components such as optical instruments, optical lenses, and prisms. At the same time, when used as a container, the internal reaction can be clearly observed, which is convenient for experimental operation and monitoring.

4. Low expansion coefficient and dimensional stability

Quartz glass tubes have a very small coefficient of thermal expansion and can withstand severe temperature changes without breaking easily. Even if the quartz glass tube is heated to about 1100 ° C and quickly put into room temperature water, it will not burst. This low coefficient of expansion and excellent dimensional stability make quartz glass tubes widely used in precision instruments and equipment. When used as a container, it can ensure that a stable shape and size are maintained in an environment with high temperature or large temperature changes, thus ensuring the accuracy and reliability of the experimental or production process.

5. Good electrical insulation properties

The resistance value of quartz glass tubes is equivalent to ten thousand times that of ordinary glass and is an excellent electrical insulating material. It has good electrical properties even at high temperatures, which makes quartz glass tubes of great significance in the manufacture of electronic components. For example, it can be used in the manufacture of high-frequency electronic equipment, high-voltage capacitors, etc. Although this property may not be directly required when used as a container, its electrical insulating properties also provide additional security for the application of quartz glass tubes in special environments.

6. Wide range of application fields

Due to the above-mentioned excellent properties of quartz glass tubes, they are widely used in many fields. In the field of lighting, they can be used to make halogen lamps, mercury lamps, xenon lamps and other lamps; in the field of heating, they can be used to make infrared heaters, ultraviolet heaters, etc.; in the field of scientific research, they are often used in tube furnaces, chemical reactors and other equipment; in the semiconductor industry, they are used as containers for epitaxy, diffusion and other links; in industrial production, they are used in ovens, drying equipment, etc. In addition, quartz glass tubes are also used in aquarium heaters, quartz tube foot warmers and other daily necessities.

Quartz glass tubes for containers play an important role in many fields due to their significant advantages such as high temperature resistance, corrosion resistance, high transparency, low coefficient of expansion and good electrical insulation properties. With the continuous progress of science and technology and the rapid development of industry, the application prospects of quartz glass tubes will be broader.
