Quartz crucible is an indispensable high-purity consumable in photovoltaic crystal pulling and semiconductor manufacturing. As a professional manufacturer of customized quartz products, we provide wholesale services for high-purity and high-temperature resistant quartz crucibles worldwide. Whether it is a large-sized crucible used for single crystal silicon drawing or a micro crucible used in experiments, we can provide you with a one-stop solution from customized design to mass production based on high-quality quartz sand raw materials and advanced arc melting technology.

Regarding the procurement of quartz crucibles, you may be concerned about the following:

I am a procurement manager in the photovoltaic industry. Can your crucible solve the impurity problem during the crystal pulling process?

Absolutely possible. Our quartz crucible uses high-purity quartz sand as raw material, and the purity of SiO ₂ can reach over 99.99%. Through strict magnetic separation and acid washing processes, the content of alkali metals such as Fe, Al, Na, etc. is effectively controlled. At the same time, we have optimized the inner transparent layer structure of the crucible (3-5mm), greatly reducing the contamination and breakage of silicon liquid caused by bubble rupture during high-temperature crystal pulling process, ensuring the success rate of your single crystal growth.

Will the crucible be prone to deformation or cracking under high temperature conditions?

Our product has an extremely low coefficient of thermal expansion and excellent thermal shock stability. Even under high temperature conditions of 1000 ℃ -1500 ℃, repeated rapid cooling and heating can maintain structural stability, without cracking or deformation, effectively extending the service life of the crucible in the single crystal furnace and helping you reduce non silicon costs.

What sizes can the factory offer for customization? Is the minimum order quantity high?

We support full-size customization, whether it's small batch samples or large batch supply.

-Specification range: It can be produced from small crucibles used in laboratories (such as 50mm diameter) to large-sized crucibles used in the photovoltaic/semiconductor industry (such as 16 inches, 18 inches, 20 inches and above).

-Shape customization: Not limited to standard round bottoms, square polycrystalline silicon ingot furnace crucibles or special shaped crucibles can also be customized according to your thermal field drawings.

-Flexible delivery: Supports mixed batch procurement, quick sampling based on drawings and samples.

Customer Application Cases

To help you gain a more intuitive understanding of the value of our products, we would like to share a typical collaboration case as follows:

-Customer requirements:

A cutting-edge photovoltaic module enterprise from Europe frequently encountered early softening and deformation of quartz crucibles during the single crystal silicon drawing process, resulting in the inability of single crystal silicon rods to achieve the goal of multiple drawing cycles (one crucible per ladle) with one feeding, seriously affecting production capacity and increasing the proportion of non silicon costs.

-Our solution:

For its thermal field size (26 inches), we recommend a customized high life synthetic quartz crucible. We adjusted the bubble layer structure of the crucible: the outer layer retained micro dense bubbles to enhance insulation, while the inner layer increased the thickness of the high-purity transparent layer (from 2mm to 4mm), and optimized the control of hydroxyl content to improve high-temperature viscosity.

-Final effect:

After two rounds of sample testing, the customer's single furnace pulling success rate increased by nearly 20%. The temperature resistance time of the crucible has been extended from the original 80 hours to over 120 hours, perfectly realizing the process change of "one crucible, multiple pots", and significantly reducing the production cost of a single ton of silicon rod. The customer has currently signed an annual long-term contract with us.

Whether you require large-scale standardized photovoltaic crucibles, small batches, high-precision semiconductors, or laboratory special specifications, we can provide you with the most suitable solutions based on our professional customization experience and stable supply chain.
