Our Products
From standard fused quartz tubing to precision-engineered custom assemblies, FGQuartz supplies a complete range of high-purity products for demanding industrial applications.
quartz glass tubes
High-purity tubes for diffusion furnaces, CVD equipment and optical fiber production. OD 5–1000 mm with excellent concentricity and uniform wall thickness.
quartz glass rod
Solid fused silica rods precision-ground to tight tolerances. Used for fiber preforms, laboratory stirring and structural support components.
quartz glass plate
Optical-grade polished plates and windows in JGS1, JGS2 and JGS3 grades. High flatness and broad UV-to-IR transmission.
Quartz Boat
Semiconductor-grade wafer boats for 2–12 inch wafers. Precise slot spacing, low particle generation and uniform thermal performance.
Quartz Crucible
High-purity crucibles for CZ and DS silicon crystal growth, chemical analysis and high-temperature melting applications.
Custom quartz glass
Fully custom components manufactured to your drawing. CNC machining and oxy-hydrogen flame forming for complex geometries.
Technical Excellence
Our high-purity fused silica delivers the critical material properties required by advanced manufacturing processes.
Thermal
Continuous use up to 1200 °C, short-term to 1300 °C. Softening point ≈ 1680 °C. Ultra-low thermal expansion (5.5 × 10⁻⁷ /°C).
Optical
Broad transmission from deep UV to near-IR. Available in JGS1, JGS2 and JGS3 grades for wavelength-specific needs.
Mechanical
High hardness, excellent dimensional stability and superior thermal shock resistance under rapid temperature changes.
Chemical
Exceptional resistance to most acids and solvents (except HF and hot phosphoric acid). Minimal ion leaching.
Industry Applications
Semiconductor
Process tubes, wafer boats, gas injectors and wet-bench components for oxidation, diffusion and LPCVD processes.
Solar Photovoltaic
CZ and DS crucibles, diffusion tubes and wafer boats supporting high-efficiency solar cell manufacturing.
Optical & Photonics
Windows, lenses, prisms and UV-grade components for laser systems, lithography and spectroscopy.
Fiber Optic
MCVD/VAD substrate tubes, preform rods and jacketing tubes for low-attenuation optical fiber production.
Laboratory
High-purity beakers, crucibles, cuvettes, reaction vessels and custom labware for analytical and research work.
High-Temperature Industrial
Furnace tubes, observation windows, supports and thermal process components for continuous high-temperature use.
