Product Overview
Felix Glass is a professional custom quartz crucible manufacturer and OEM optical quartz fabrication supplier, providing semiconductor-grade precision optical quartz components for polysilicon manufacturers, laboratory analytical equipment suppliers, photovoltaic sintering factories and precious metal melting workshops worldwide. Our quartz crucibles are manufactured from 99.99% ultra-high purity fused silica with JGS2 and JGS3 material grades, featuring extremely low metal impurity content, ultra-low CTE and excellent high-temperature stability. The dense quartz structure effectively avoids sample contamination during high-temperature melting, sintering and chemical digestion processes. These crucibles are core containers for semiconductor silicon melting, photovoltaic wafer sintering, lab ICP analysis and precious metal smelting.We support custom inner volume, wall thickness, lid matching and special bottom profiling processing, fully compliant with semiconductor purity standards and ISO 9001 full inspection, covering small lab analytical crucibles to large industrial OEM melting vessels.
