High-purity quartz crucibles for semiconductor crystal growth and solar silicon

What Are Fused Quartz Crucibles?

A fused quartz crucible is a high-purity container made from fused silica, used primarily in the Czochralski (CZ) process for growing single crystal silicon ingots. As a core high-temperature quartz crucible, it must withstand extreme temperatures over 1400°C and maintain structural stability during prolonged crystal growth cycles.

Due to strict requirements on impurity levels and thermal behavior, the fused quartz crucible is one of the most critical consumables in semiconductor and solar industries, and is also widely used as a laboratory quartz crucible for high-purity material melting in scientific research.

Key Advantages of Our Fused Quartz Crucible Products

Ultra High Purity

SiO₂ ≥ 99.99%, extremely low metallic contamination, the core standard for semiconductor-grade fused quartz crucible and precision laboratory quartz crucible products.

Low Bubble Content

Controlled bubble distribution improves silicon crystal quality and production yield for both semiconductor and photovoltaic applications.

High Thermal Stability

Stable under extreme thermal gradients in the CZ process, the key performance of our industrial high-temperature quartz crucible range.

Long Service Life

Optimized structure reduces high-temperature deformation and extends usage cycles for repeated production runs.

Uniform Wall Thickness

Ensures stable melting and consistent crystal growth conditions for every fused quartz crucible produced by our team as a professional quartz crucible manufacturer.

Low Contamination Risk

Minimizes oxygen and impurity transfer to silicon ingots, critical for high-purity semiconductor and laboratory applications.
