Custom-Shaped Quartz Glass Plates for High-Temperature and Corrosive Environments

Introduction of quartz glass plates

Our custom-shaped quartz glass plates are engineered for extreme-performance environments where traditional materials fail. Made from ultra-pure fused silica (SiO₂ ≥ 99.99%), these plates offer exceptional resistance to high temperatures, rapid thermal cycling, chemical corrosion, and optical degradation.

From protective windows in plasma chambers to UV-transparent covers in photonics and chemical-resistant viewports in analytical systems, we provide precision-fabricated quartz plates tailored to your exact specifications—shape, size, thickness, finish, and performance.

Applications of quartz glass plates

Our quartz glass plates are used across diverse industries where clarity, strength, and resistance to heat and corrosion are mission-critical.

1. Vacuum and Thermal Furnaces

Quartz plates are used as viewports or insulation barriers in vacuum chambers and high-temperature tube or muffle furnaces.

2. Semiconductor Fabrication

Quartz components serve as cover windows, carrier substrates, or chamber liners in CVD, PECVD, and dry etch processes.

3. UV and IR Optical Systems

Because quartz transmits from deep UV (200 nm) to infrared (3.5 μm), it’s ideal for UV curing, laser optics, and thermal imaging.

4. Chemical Processing and Fluid Analysis

Used as reaction windows, flow cell covers, or sensor shields in highly corrosive or acidic conditions.

5. Solar & Green Energy Systems

Quartz serves as light-transmitting covers for CSP tubes, PV concentrators, or high-performance solar receivers.

6. Aerospace and Defense

In harsh or high-altitude conditions, quartz shields thermal sensors, targeting optics, or onboard analytical equipment.

7. Analytical and Medical Instruments

Used as transparent, inert windows or sample holders in XRF, spectroscopy, TGA, or bioassay setups.
