1、 High purity and chemical stability

Quartz crucible is made of silicon dioxide (SiO2), which has extremely high purity and usually has very low impurity content. This high purity endows quartz crucibles with excellent chemical stability, making them resistant to most acids, bases, and other corrosive substances at high temperatures, making them an ideal choice for processing high-purity materials in the semiconductor industry and laboratories.

2、 High temperature resistance performance

Quartz crucibles have a very high melting point of approximately 1713 degrees Celsius and can withstand higher temperatures without deformation or softening in practical applications. This characteristic is particularly important for experiments and industrial processes that require high temperature environments, such as during crystal growth, quartz crucibles can ensure the integrity of the container and provide a pure and pollution-free growth environment for crystals.

3、 Small coefficient of thermal expansion

Quartz material has a relatively small coefficient of thermal expansion, which means that its size changes relatively little with temperature. This is very important for processes that require high dimensional accuracy, such as the drawing process of single crystal silicon or polycrystalline silicon, where a stable crucible volume helps ensure consistency and stability in crystal quality.

4、 Transparency and Visible Light Transmittance

Quartz crucibles are semi transparent to transparent, allowing operators to observe internal reactions with the naked eye, especially when conducting optical measurements or monitoring reaction processes. In addition, quartz crucibles also have good ultraviolet transmission ability, which is suitable for some special photochemical reaction research.

5、 Moderate mechanical strength

Although quartz is a brittle material, crucibles made through appropriate processing still have a certain mechanical strength, which is sufficient for handling and operation in daily use. Meanwhile, due to its high hardness, the quartz crucible is not easily scratched, thereby reducing the risk of contamination caused by surface damage.

6、 Environmental Protection and Safety

Quartz crucibles do not contain harmful substances such as heavy metals, and are environmentally friendly during production and use, meeting the requirements of modern industry for environmental protection. Moreover, due to its chemical stability and low toxicity, it will not release toxic gases even under high temperature conditions, ensuring the safety and health of workers.

Quartz crucibles play an indispensable role in many fields, especially in high-tech industries, due to their unique physical and chemical properties. Whether used for scientific research or industrial production, quartz crucibles meet the demands of various harsh conditions with their excellent performance.
