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.

Specifications of quartz glass plates

Q&A

Q1: Can I get a custom hole, notch, or slot in the quartz plate?

Yes! We support precision CNC cutting, laser drilling, and shaped edges according to your CAD drawing or specifications.

Q2: Are coatings available for better optical performance?

Yes. We offer anti-reflective (AR), UV-enhancing, IR-pass, and protective coatings. Dual- or multi-band coatings are also available.

Q3: What’s the typical lead time for custom plates?

• Standard sizes: 3–7 business days

• Custom-cut / CNC-processed: 7–15 business days

• Optical coatings: Add 3–5 days

Q4: Do you support large batch production?

Yes! We provide volume manufacturing, including tooling and private labeling for OEM customers.

Q5: How are plates cleaned and packaged?

All plates are ultrasonically cleaned, inspected in cleanroom environments, and packaged in anti-static or vacuum-sealed containers. Foam or cassette packaging is available for bulk orders.

Q6: Are these plates compatible with high-vacuum or plasma systems?

Yes. Fused quartz is non-outgassing and suitable for UHV and plasma exposure, making it ideal for semiconductor and analytical equipment.
