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

Explore how fused quartz components are enabling reliability and innovation across industries:

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.

Semiconductor & Microelectronics Manufacturing

Used in plasma etching chambers, wafer handling fixtures, and photolithography tools, quartz provides purity, chemical resistance, and dimensional precision.

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.

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

Solar Energy & Concentrated Light Systems

As a protective and transmissive barrier, quartz glass enables the long-term performance of solar receivers, concentrators, and photovoltaic modules under extreme heat and UV.

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.

Medical Diagnostics & Lab Equipment

Quartz offers thermal and chemical inertness in instruments such as spectrophotometers, cuvettes, and TGA/DSC systems used in clinical and research applications.

Technical Specifications

Frequently Asked Questions

Q1: Can you produce custom shapes based on a drawing?
Yes. We accept detailed drawings or CAD files and can fabricate complex geometries including holes, bevels, or internal features.

Q2: What’s the difference between fused quartz and fused silica?
They are functionally similar. Fused silica is synthetically produced from high-purity gas-phase precursors and often used in optical applications. Fused quartz is naturally derived and generally preferred for industrial use.

Q3: Do you offer polishing or coating services?
Yes. We offer single- or double-sided polishing, AR coating, and other optical treatments upon request.

Q4: What is the minimum order quantity (MOQ)?
There is no strict MOQ for prototypes. For production runs, pricing is optimized for quantities above 10 pcs.

Q5: Can parts be cleaned and packaged for cleanroom environments?
Yes. We offer ultrasonic cleaning and cleanroom packaging options (Class 100 or better).
