Q: As a purchaser or user, do you face the following issues?

-Need high-purity and high-temperature resistant quartz crucibles, but market products are difficult to meet precise chemical stability and thermal shock requirements?  

-Special processes such as monocrystalline silicon growth and high-temperature melting experiments have unique requirements for crucible size and shape, but cannot find flexible customized suppliers?  

-Worried about impurities in the crucible affecting product quality, or frequent replacement leading to increased production costs?  

-When purchasing overseas, slow supply chain response and poor communication affect production progress?  

Answer: We specialize in customized quartz crucible processing, targeting the core pain points directly——

We provide high-purity quartz raw materials (SiO ₂ ≥ 99.99%), high-temperature resistant (above 1200 ℃), corrosion-resistant crucibles, and support full-size customization to ensure stability and lifespan, helping you reduce costs and increase efficiency!

Application scenarios

Quartz crucibles are widely used in high-end manufacturing and scientific research fields due to their excellent thermal stability and chemical inertness

-Photovoltaic and semiconductor industry: monocrystalline silicon and polycrystalline silicon growth containers to ensure crystal purity and production efficiency.  

-Laboratories and research institutions: high-temperature melting, chemical analysis, material synthesis experiments to ensure data accuracy.  

-In the field of optoelectronics and new materials: laser crystal and optical glass preparation, resistant to extreme process environments.  

-Metal and ceramic processing: precious metal purification, high-temperature sintering process to avoid impurity contamination.  

Why are our quartz crucibles more reliable?  

1. High purity material: Natural quartz sand or synthetic quartz is used, with an impurity content of less than 10ppm to prevent sample contamination.  

2. Excellent thermal performance: Low coefficient of thermal expansion (5.5 × 10 ⁻⁷/℃), high temperature resistance up to 1200 ℃~1450 ℃, and no cracking during rapid cooling and heating.  

3. Precision technology: CNC cutting, laser engraving, and fire polishing techniques ensure dimensional accuracy and inner wall smoothness.  

4. Strong corrosion resistance: acid resistant (except hydrofluoric acid), alkali resistant, suitable for complex chemical environments.  

Comprehensive customization service: flexible adaptation to size, shape, and craftsmanship

-Specification range: Diameter 10mm~600mm (expandable), depth and wall thickness can be adjusted as needed.  

-Shape customization: standard circular, square, and irregular designs (such as covered, porous, and tapered bottom).  

-Process enhancement: Additional coatings (such as yttrium oxide), high-purity polishing, and vacuum defoaming treatment can be applied.  

Core problem solved

-Purity hazard: strict screening of raw materials+dust-free workshop production to prevent secondary pollution.  

-Shortage: Optimizing annealing process, improving mechanical strength, and increasing service life by more than 30%.  

-Low customization efficiency: CAD drawing docking, flexible production line, small batch minimum order, no minimum order limit.  

-Cross border procurement pain points: Multi language team support, providing qualification certification (ISO9001, RoHS) and integrated export customs clearance services.
