Quartz tubes are materials widely used in scientific research and industrial production. They are characterized by high purity and excellent physical and chemical properties, making them extensively applicable in fields such as optoelectronics, electronics, chemistry, and biology. Dehydroxylation is a process that removes hydroxyl groups from the surface of quartz tubes, enhancing their surface purity and optical performance.

The presence of hydroxyl groups on the surface of quartz tubes results from reactions with water molecules during the manufacturing process. These hydroxyl groups can affect the properties and applications of the quartz tubes. Therefore, to improve the performance of quartz tubes, it is necessary to remove these surface hydroxyl groups. There are various methods of dehydroxylation, with thermal treatment and chemical treatment being the most common.

Thermal treatment is a prevalent method of dehydroxylation. Under high temperatures, quartz tubes undergo thermal decomposition, where hydroxyl groups are broken down and released as water molecules, detaching from the surface of the tube. The advantage of this method is its simplicity and effectiveness, but it requires high temperatures and extended time to completely remove the hydroxyl groups. Additionally, thermal treatment may cause changes in the dimensions and crystal structure of the quartz tubes, affecting their performance.

Chemical treatment is another common method of dehydroxylation. Typical chemical agents include acids, bases, and hydrofluoric acid. These chemicals react with the hydroxyl groups on the surface of the quartz tubes, effectively removing them. The advantages of chemical treatment include lower temperature requirements and more thorough removal of hydroxyl groups. However, this method also presents some challenges, such as the selection of treatment agents and the occurrence of side reactions.

Beyond thermal and chemical treatments, other methods are also used for dehydroxylation. For instance, plasma treatment is a newer method that uses plasma at low temperatures to remove surface hydroxyl groups. Additionally, methods like the sol-gel process and sintering can be used to manufacture quartz tubes without hydroxyl groups.

Dehydroxylation is an essential treatment method for quartz tubes, enhancing their performance and broadening their application scope. Thermal and chemical treatments are common dehydroxylation methods, each with its advantages and disadvantages. Moreover, other methods are also available for dehydroxylation. In practice, the choice of dehydroxylation method should be based on specific circumstances. With ongoing advancements in science and technology, dehydroxylation methods will continue to evolve and innovate, offering expanded possibilities for the research and application of quartz tubes.
