High Purity Quartz Crucible for Solar & Semiconductor | 12″-32″ Arc Fused
Optimized for the Czochralski (CZ) process, our arc-fused quartz crucibles feature a premium bubble-free inner layer to maximize crystal yield and purity. With superior heat resistance at 1450°C and ultra-low metallic impurities, these crucibles are the trusted choice for high-volume Solar and Semiconductor wafer production.
Product Overview
Our High-Purity Quartz Crucibles are manufactured using the advanced arc-fusion process, specifically designed for high-temperature melting and crystal pulling. These crucibles offer exceptional thermal stability, ultra-low thermal expansion, and the highest chemical purity available in the industry.
Whether used in laboratory material synthesis or large-scale monocrystalline silicon growth, our crucibles provide a stable, contamination-free environment. We offer a full range of custom sizes (from 12 inches to 32 inches) with specific wall thicknesses and structural designs to meet the rigorous demands of the semiconductor and PV solar industries.
Key Features
- Ultra-High Purity Material:SiO2 >= 99.995% to ensure zero contamination of the silicon melt.

FAQ – Quartz Crucible
Q: Can your quartz crucibles withstand repeated heating cycles? Yes. Our high-purity fused quartz provides excellent thermal stability for repeated use in many industrial melting processes.
Q: Do you offer large-diameter crucibles for solar ingot growth? Absolutely. We provide standard and custom sizes up to 32 inches, specifically designed for large-scale CZ furnaces.
Q: How do you prevent contamination during shipping? Every crucible is individually vacuum-packed and crated using export-grade protective materials to ensure “out-of-the-box” cleanliness.
