Small caliber transparent quartz crucible

The small-diameter transparent quartz crucible is a high-temperature resistant container specially designed for precision experiments and high-end manufacturing. It is made of high-purity quartz raw material, with excellent transparency and thermal stability, and can work stably for a long time in high temperature environments ranging from 1200 ℃ to 1450 ℃. Its clean and homogeneous characteristics make it an ideal choice for harsh scenarios such as crystal growth, material heat treatment, and chemical analysis.

FAQ

Q: What is the maximum temperature that a small-diameter transparent quartz crucible can withstand?

A: Our quartz crucible has a softening point of approximately 1730 ℃, with a maximum continuous operating temperature of 1100 ℃ to 1200 ℃. It can withstand high temperatures up to 1450 ℃ in a short period of time, fully meeting the needs of most high-temperature experiments and production.

Q: Do you support customization of special specifications in addition to regular sizes?

A: Yes, we provide professional customization services. We can accurately customize parameters such as capacity (10ml to 1000ml and above), caliber size, height, wall thickness, etc. according to your specific process requirements.

Q: Can transparent quartz crucibles come into contact with hydrofluoric acid or strong alkali?

A: The main component of quartz is silicon dioxide, which has excellent corrosion resistance to ordinary dilute inorganic acids, except for hydrofluoric acid. But at high temperatures, it is highly prone to react with caustic soda and alkali metal carbonates, so it is not recommended to use it in such environments.

Q: What is the difference between fully transparent structure and semi transparent structure, and how to choose?

A: The fully transparent crucible has extremely high light transmittance, making it convenient for real-time optical monitoring during the experimental process; The semi transparent (or bubble layer) structure can provide more uniform thermal radiation conditions in industrial crystal pulling. We will recommend the most suitable material structure for you based on your specific application scenario.

Addressing your core needs

This product mainly solves the problems of "visualization" and "high purity" in high-temperature environments for you. The high transparency design allows you to observe the melting, crystallization, or reaction status of internal samples at any time, just like installing a high-definition camera; The extremely high chemical purity and thermal stability effectively avoid contamination of the sample by the container itself, ensuring the accuracy and reliability of experimental data and product quality.

Application and core advantages

Small aperture transparent quartz crucibles are widely used in semiconductor single crystal drawing, photovoltaic industry, optical glass melting, high-temperature solid-state reactions, material purification, and various laboratory high-temperature sintering and annealing processes.

The core advantage of our product lies in:

Excellent thermal performance: Its extremely low coefficient of expansion gives it excellent thermal shock resistance and the ability to withstand rapid temperature changes without easily breaking.

Extremely high chemical purity: using high-quality quartz raw materials with extremely low metal impurity content, effectively ensuring the crystallization rate and quality of high-end materials such as silicon rods.

Comprehensive customization service: As the source manufacturer, we provide deep customization from diameter, height to irregular structures, flexibly matching the diverse production lines and experimental needs of global customers.

Why choose us

We are a professional quartz product manufacturer with many years of experience, providing one-stop solutions from research and development, production to after-sales service to global customers. We not only have a strict quality inspection system to ensure the purity and strength of every crucible leaving the factory, but also have strong non-standard customization capabilities to provide you with the most cost-effective products and services.

Customer Application Cases

The materials laboratory of a certain university is facing a severe challenge in researching the preparation process of new optical glass: it is necessary to melt trace samples at a high temperature of 1300 ℃ for several hours, and real-time spectral analysis must be performed from the bottom. Ordinary ceramic crucibles cannot meet the requirement of transparency, while conventional quartz vessels on the market are prone to deformation and even impurity precipitation under prolonged high temperatures.

After understanding its specific working conditions, we customized a batch of small-diameter transparent quartz crucibles with special optical polishing at the bottom. After being put into use, the laboratory successfully achieved full process visualization monitoring of the melting state, and the crucible maintained extremely high dimensional stability and cleanliness in repeated high-temperature experiments, greatly improving the accuracy of its scientific research data and experimental efficiency.
