Quartz glass rods are a special glass material made of pure silicon dioxide (SiO2) with a series of unique chemical stability characteristics:

1. Acid resistance: quartz glass rods show extremely high inertness to most acids, except hydrofluoric acid (HF) and hot phosphoric acid, almost all other acids do not react, which makes it the best of the acid-resistant materials.

2. Alkali Resistance: Although quartz glass rods are stable to most acids, they are less resistant to alkalis. At high temperatures, quartz glass may react with alkalis, resulting in a loss of material properties.

3. Thermal stability: quartz glass rods have excellent thermal stability and can be used for long periods of time at temperatures up to 1000°C or more without loss of transparency or crystallization.

4. Low Coefficient of Thermal Expansion: Quartz glass rods have a very low coefficient of thermal expansion, which means that they have very little volume change under temperature change, making them suitable for use in applications that require precise dimensional control.

5. Irradiation resistance: quartz glass rods have excellent resistance to irradiation by gamma rays, X-rays, etc., which allows them to be used in radioactive environments.

6. High purity: High purity quartz glass rods contain virtually no impurities, which is very important in semiconductor manufacturing and scientific research, because even very small amounts of impurities may affect the performance of the device.

7. Water resistance: quartz glass rods have a very high chemical stability to water, can be used in water distillers and other equipment requiring very high water purity.

8. Resistance to organic solvents: quartz glass rods also exhibit good chemical stability to most organic solvents, making them suitable for use in chemical synthesis and processing.

9. Weathering resistance: Quartz glass rods do not absorb moisture or weather, and maintain their performance even in humid environments.

10. Hydroxyl Content: The hydroxyl (OH) content in quartz glass rods affects their chemical stability and optical properties. The presence of hydroxyl groups may reduce the heat resistance and optical uniformity of quartz glass.

Therefore, quartz glass rods are widely used in many high-tech fields, such as semiconductor manufacturing, optical communication, electric light source, military, metallurgy, chemical industry and other industries due to its excellent chemical stability and physical properties.
