MatMeas High-Purity Quartz Crucible Specifications
The MatMeas High-Purity Quartz Crucible is engineered for precision single crystal growth applications in semiconductor wafer and solar photovoltaic manufacturing.
Constructed from premium fused silica (SiO₂ >99.99%), our crucibles offer exceptional thermal shock resistance and maintain structural integrity under extreme temperatures up to 1500°C. The low aluminum and alkali metal content minimizes contamination risks during silicon ingot pulling processes.
Available in both transparent and opaque configurations, with customizable dimensions to fit mainstream crystal pullers (CGS, Kayex, etc.). OEM/ODM services available for wholesale orders.
