High Purity Quartz Glass Products & Custom Fused Silica
FGQuartz supplies premium quartz glass products and fused silica for semiconductor, optical fiber, laboratory and high-temperature industries. As a dedicated quartz glass supplier since 2005, we offer standard parts and custom quartz fabrication — all in high-purity fused silica and held to tight tolerances.
Complete Quartz Glass Product Portfolio
We manufacture a full series of high-purity fused silica products with precise tolerances. Our quartz glass products are widely used in semiconductor processing, optics and laboratory research.
High-precision quartz glass tubes for diffusion furnaces, CVD equipment and optical fiber production. Diameters 5–1000 mm, with stable wall thickness and excellent concentricity for high-temperature use.
Solid fused quartz rod with strong thermal stability and clear optical performance. Diameters 3–300 mm, used for fiber preforms, laboratory stirring and industrial support parts.
Optical-grade polished quartz plate with fine flatness and high light transmittance. Ideal for observation windows, substrates and high-temperature industrial viewing components.
Semiconductor quartz boat for 2–12 inch wafer processing in oxidation and diffusion furnaces. It offers low contamination, precise slot spacing and uniform heating.
High purity quartz crucible that resists corrosion and high heat. It is used in chemical analysis, melting and crystal-growth experiments, with multiple volume options.
Custom quartz glass parts built to your drawings. We provide CNC machining, flame working and fire polishing — from single prototypes to volume production of complex fused silica components.
Material Standards Across Our Quartz Glass Products
Every product line meets the same fused silica standards. The glass is high-purity fused silica, with a softening point of about 1680°C and continuous service temperature up to 1200°C. We supply clear and opaque grades, plus JGS1 and JGS2 optical grades, verified by ICP-MS analysis on each batch.
High-Purity Fused Silica
High-purity material for semiconductor, optical and laboratory-grade fused silica products.
Up to 1200°C Service
Continuous use to 1200°C with a softening point near 1680°C for demanding thermal work.
Tight Tolerances
CNC-machined precision and CMM checks ensure consistent dimensions on every order.
Where Our Quartz Glass Products Are Used
Our quartz tube and rod, plates, crucibles, boats and custom quartz components serve six major industries: semiconductor manufacturing, solar photovoltaic, optical and laser systems, fiber optic production, laboratory research, and high-temperature industrial heating.
