Quartz crucible manufacturer

Q: Why does my high-temperature process always experience impurity contamination or crucible rupture?  

A: Because ordinary containers cannot withstand extreme temperatures and chemical corrosion. Our high-purity quartz crucible is made of 99.99% or more pure fused silica, with temperature resistance up to 1650 ° C, strong thermal stability and excellent thermal shock resistance, which can effectively avoid the precipitation of metal/non-metallic impurities, and ensure your process purity and production continuity in semiconductor, photovoltaic, laboratory and other key fields.

The product has a wide range of applications and accurately matches industry needs

As a professional quartz crucible manufacturer, we provide global customers with high-performance quartz crucible solutions suitable for multiple industries:

-Photovoltaic industry: used for the pulling and casting process of monocrystalline silicon and polycrystalline silicon, ensuring the purity of silicon materials and improving the conversion efficiency of batteries.  

-Semiconductor manufacturing: used as a core consumable in CZ (Czochralski) crystal growth to prevent metal contamination and ensure wafer quality.  

-Laboratory research: Suitable for scenarios such as high-temperature melting, sample digestion, and material synthesis, meeting analytical grade cleanliness requirements.  

-Special glass and ceramic sintering: providing a pollution-free, high transparency, and low expansion reaction environment.  

-Metallurgy and new material research and development: used for purification and melting of rare earths and high-purity metals.

Core Product Advantage: Technology+Materials+Process Trinity

1. Ultra high purity raw materials

Selected natural crystals or synthetic high-purity SiO ₂, with total metal impurities controlled below 10ppm.

2. Advanced molding technology

Adopting arc melting+precision spinning/molding technology, the structure is dense and uniform, without bubbles or cracks, and the wall thickness tolerance is within ± 0.5mm.

3. Excellent thermal performance

-Operating temperature: up to 1650 ° C (short-term up to 1700 ° C)

-Thermal expansion coefficient: only 0.55 × 10 ⁻⁶/° C (20-320 ° C)

-Thermal shock resistance: can withstand rapid cooling from 800 ° C to room temperature without cracking

4. Strong chemical inertness

Acid resistant (except HF), alkali resistant, and does not react with most molten metals/oxides to ensure the purity of the process medium.

Full size customization service, flexible response to global customer needs

We are well aware that different application scenarios have unique requirements for the shape, capacity, opening method, and bottom structure of the crucible. Therefore, providing 100% customized services:

-Capacity range: 50ml to 500L (laboratory small crucible to industrial large crucible)

-Common specifications: diameter ranging from 50mm to 800mm, height ranging from 50mm to 1000mm

-Special design: spout tilting, double-layer jacket, irregular bottom, perforated exhaust, thickened wall, etc

-Surface treatment: optional options include polishing the inner wall (reducing material hanging), sandblasting the outer wall (enhancing heat dissipation), etc

Customer Application Case (Anonymous)

-A leading photovoltaic enterprise in Europe has customized a large-sized quartz crucible with a diameter of 600 × 800mm for N-type TOPCon silicon rod drawing, which has increased the continuous use by 20% and the yield by 1.8%.  

-Top Semiconductor Materials Research Institute in North America: Developed a quartz crucible with microporous exhaust structure for its new compound semiconductor project, successfully solving the problem of bubble inclusion.  

-Southeast Asian new energy manufacturer: Bulk purchase of Φ 300 series crucibles for melting perovskite precursors, achieving 6-month zero damage operation.
