Fused Quartz Glass Components – Precision-Crafted for Extreme
Conditions
Product Overview
Fused quartz glass offers unmatched durability and performance in
demanding environments where ordinary materials fail. Formed from
ultra-pure silicon dioxide (SiO₂), it boasts superior thermal
stability, corrosion resistance, and broad-spectrum optical
transmission. Our custom-shaped quartz glass plates are engineered
to support high-precision systems in critical applications—whether
exposed to thermal stress, chemical attack, or ultraviolet
radiation.
From R&D laboratories to industrial cleanrooms, each piece is
crafted to exact specifications, ensuring consistent performance
and compatibility. Available in a wide range of geometries and
finishes, our quartz glass solutions are ideal for integration into
optical instruments, process equipment, and thermal systems.
Industrial Applications of Fused Quartz
Fused Quartz in High-Temperature Furnaces & Kilns
Quartz plates act as viewing windows, thermal barriers, and
structural components in vacuum and atmosphere-controlled furnaces
operating above 1000°C.
Fused Quartz in Semiconductor & Microelectronics Manufacturing
Used in plasma etching chambers, wafer handling fixtures, and
photolithography tools, quartz provides purity, chemical
resistance, and dimensional precision.
Fused Quartz in UV & IR Optical Equipment
Quartz maintains high transmission across ultraviolet to infrared
wavelengths, making it ideal for laser optics, sterilization lamps,
and IR detection systems.
Fused Quartz in Chemical Processing & Analytical Systems
Non-reactive and transparent, quartz serves as a critical component
in reactors, flow cells, and analytical instruments exposed to
acids, solvents, and elevated temperatures
Fused Quartz in Aerospace & Optical Sensing
Quartz glass is used in protective sensor windows, optical lenses,
and viewing panels for high-altitude and aerospace environments
that demand resilience and clarity.
Key Advantages of Fused Quartz
✔Fused quartz's Extreme Temperature Stability
Performs reliably at temperatures exceeding 1000°C, with a melting
point above 1700°C.

or process environments.
✔Fused quartz's Optical Precision Across Spectra
High transmission from UV (200 nm) through visible and IR (~3500
nm).
✔Fused quartz's Custom Geometry Compatibility
Shapes include discs, squares, slots, cut-outs, and fully contoured
parts based on your CAD.
✔Fused quartz's Clean and Pure
Produced from synthetic or natural high-purity quartz with minimal
trace metals.
✔Fused quartz's Tight Dimensional Control
Machining tolerances down to ±0.01 mm and surface flatness up to
λ/10 available.
✔Fused quartz's Coating Ready
Compatible with AR, UV-enhanced, or hydrophobic coatings as needed.
