Due to its low coefficient of thermal expansion, good heat resistance, excellent chemical stability, and light transmittance, quartz glass tubes are widely used in a variety of fields. Here are some specific examples of thermal expansion applications:

1. Thermometer manufacturing: Quartz glass tubes can be used to make high-precision thermometers because they have a small coefficient of expansion when the temperature changes, allowing them to accurately reflect temperature changes.

2. Optical instruments: In optical instruments, quartz glass tubes can be used as key optical components because of their low coefficient of thermal expansion, which allows them to maintain the stability and accuracy of the optical system during temperature changes.

3. Thermocouple protection sleeve: In high temperature measurement, the sleeve of a thermocouple usually uses a quartz glass tube because it protects the thermocouple from the atmosphere and has good thermal expansion matching to ensure measurement accuracy.

4. Laboratory instruments: When manufacturing various laboratory instruments, such as test tubes, beakers, distillers, etc., quartz glass tubes can withstand temperature differences and are not easily cracked.

5. Semiconductor manufacturing: In the semiconductor manufacturing process, quartz glass tubes can be used as transmission pipes or carrier vessels because they have good dimensional stability in high temperature environments and do not affect the processing accuracy of semiconductors due to thermal expansion.

6. Fiber optic manufacturing: During the fabrication of fiber optic preforms, quartz glass tubes are used as the outer layer material to maintain the stability of shape and size during the drawing process at high temperatures.

7. High-temperature furnace internals: In high-temperature furnaces, quartz glass tubes can be used as observation windows or support structures, and their low expansion characteristics at high temperatures can reduce the stress caused by thermal expansion.

8. Lighting equipment: Quartz glass tubes are used to make high-quality lighting equipment, such as halogen lamps, because of their low coefficient of thermal expansion, they can operate at high temperatures for a long time without deformation.

These applications take advantage of the low thermal expansion of quartz glass tubes, which play an important role in applications where precise temperature control and dimensional stability are required.
