Custom High-Purity Quartz Glass

What Is High-Purity Quartz Glass?

Custom High-Purity Quartz Glass is a premium-grade, amorphous silica-based material renowned for its exceptional thermal stability, optical clarity, and chemical resistance. With a purity level exceeding 99.99% SiO₂, this material is widely used in industrial, laboratory, and semiconductor environments where reliability and precision are critical.

Unlike standard glass, fused quartz and synthetic quartz glass are manufactured through ultra-clean processes that eliminate metallic and organic impurities. As a result, they exhibit superior performance in high-temperature, UV-transmitting, and corrosive conditions.

Key Performance Benefits of High Temperature Quartz Glass

Heat Resistance up to 1200°C (and Beyond)

Engineered for continuous operation up to 1200°C and short-term exposure up to 1500°C, this material is ideal for use in thermal processing, furnaces, high-temperature reactors, and semiconductor fabrication chambers. Its extremely low thermal expansion rate (5.5 × 10⁻⁷ /°C) ensures dimensional stability and crack resistance during thermal cycling.

Excellent UV and Optical Transparency

Optical-grade quartz glass offers over 90% light transmittance in the 190–2500 nm wavelength range, including deep UV, visible, and IR spectrums. This makes it suitable for UV-transparent applications, laser systems, optical windows, and UV-curing systems.

Superior Chemical Durability

With high resistance to acids (excluding hydrofluoric acid), alkalis, and corrosive gases, this glass is ideal for chemical vapor deposition (CVD) processes, etching chambers, and fluid handling in aggressive environments.

Product Formats and Customization Options

We offer high-purity quartz glass in a wide variety of shapes and sizes, including:

Each component is fabricated under ISO-class cleanroom conditions to ensure contamination-free performance.

Applications of Quartz Glass for High Heat Applications

Laboratory and Analytical Equipment

Quartz glass is the material of choice for high-temperature crucibles, reaction vessels, burner tubes, and optical sensors in analytical chemistry, biotechnology, and materials science.

Semiconductor and Wafer Fabrication

Its thermal shock resistance and chemical purity make quartz glass indispensable for lithography, plasma etching, diffusion, and oxidation processes. Our quartz wafers are widely used in semiconductor research and production.

Optical and UV Applications

With superior UV transparency, this material is used in spectroscopy cells, laser optics, UV-transmitting windows, and light guide components.

Furnace Windows and Reaction Chambers

The glass’s ability to endure extreme temperatures without structural degradation makes it a safe and efficient material for observation windows, viewports, and reaction containment in vacuum or controlled atmosphere environments.

Corrosive Gas and Liquid Environments

Due to its resistance to hydrothermal corrosion, quartz glass is a dependable choice for fluid flow components, gas analyzers, and chemical reactors exposed to acidic or alkaline media.
