High Purity Quartz Glass Manufacturer & Custom Supplier

Quartz diffusion tubes, wafer boats, CVD reactor components and process chambers for contamination-free silicon wafer processing. FGQuartz supplies the front-end semiconductor industry with high-purity fused silica quartzware matched to major tube furnace platforms and wafer sizes from 100 mm to 300 mm.

High-purity quartz crucibles for Czochralski silicon crystal growth, diffusion tubes for solar cell emitter formation, and wafer boats for M10 and G12 solar wafer formats. FGQuartz supplies CZ crucibles from 12-inch to 32-inch and DS crucibles in G5 through G8 sizes for the full solar silicon production chain.

Fused silica optical windows, lenses, prisms, UV cuvettes, and lamp envelopes covering 150 nm deep-UV to 3.5 µm near-infrared. FGQuartz supplies JGS1 and JGS2 grade optical fused silica components for laser systems, UV sterilisation, spectroscopy instruments, and UV lithography applications.

Ultra-high purity fused silica substrate tubes and starting rods for MCVD, OVD, and VAD optical fiber preform manufacturing. Low-OH and high-OH grades for single-mode telecom fiber and specialty fiber applications. Geometric uniformity and metallic purity controlled to the levels demanded by fiber transmission performance specifications.

Research-grade quartz labware — crucibles, beakers, cuvettes, ICP plasma torches, and tube furnace hardware — for analytical chemistry, materials science, and high-temperature research. FGQuartz serves research institutions from single-piece prototype orders to volume supply without minimum order quantity.

Fused silica infrared heater envelopes, industrial furnace process tubes, thermocouple protection tubes, and high-temperature observation windows for industrial heating, chemical processing, and thermal analysis applications. Quartz glass operates continuously at 1200°C — beyond the capability of borosilicate glass, most ceramics, and engineering polymers.
