Low hydroxyl fused silica glass tube


Low hydroxyl fused silica glass tube is a kind of quartz glass tube with extremely low hydroxyl (OH) content after special processing. Hydroxyl groups are a common impurity in quartz glass, which can affect the transparency, chemical stability, and thermal stability of the glass. Low hydroxyl fused silica glass tubes have important applications in many high-tech fields and precision experiments because of their excellent physical and chemical properties.


Low hydroxyl fused silica glass tube


Material characteristics:

Low hydroxyl content: Through special processing techniques, the hydroxyl content is significantly reduced, improving the purity and performance of the glass.

High transparency: With low hydroxyl content, it reduces light scattering and therefore has high transparency.

Excellent chemical stability: The decrease in hydroxyl content enhances the glass's resistance to chemical reagents, making it less prone to chemical reactions.

High temperature resistance: able to maintain stability at extremely high temperatures, without deformation or crystallization.

Low thermal expansion coefficient: It has an extremely low thermal expansion coefficient and good heat shock resistance.

Manufacturing process:

Raw material processing: High purity quartz sand is selected, and the hydroxyl content in the raw material is reduced through special pretreatment methods.

Melting: High temperature melting technology is used to ensure complete melting of quartz sand, and the atmosphere during the melting process is precisely controlled to further reduce the hydroxyl content.

Molding: Manufacturing glass tubes of the desired shape using molding techniques such as pulldown or rotation.

Annealing: The formed glass tube needs to undergo annealing treatment to eliminate internal stress and ensure the stability and strength of the product.

Product features:

High purity: with minimal internal impurities and low hydroxyl content, ensuring the transparency and chemical stability of the glass tube.

Good thermal performance: suitable for high temperature environments and not prone to thermal cracking.

High strength: After special processing, low hydroxyl fused silica glass tube has high mechanical strength.

Application areas:

Optical instruments: used to manufacture high-quality optical components such as lenses, prisms, optical windows, etc.

Semiconductor industry: used for key steps such as etching and deposition in semiconductor manufacturing processes.

Laboratory equipment: used to manufacture high-performance laboratory vessels such as test tubes, beakers, chromatography columns, etc.

Fiber optic communication: used for manufacturing fiber optic preforms and is an important component of fiber optic communication.
