Corrosion-Resistant Quartz Glass | High Light Transmittance Window | Custom-Shaped Quartz Glass

Fused quartz glass has become an essential material across industries where extreme environmental conditions and high optical precision are demanded. Our corrosion-resistant quartz glass products are manufactured using high-purity silicon dioxide (SiO₂), processed through electric fusion, and carefully shaped into both standard and custom geometries. These glass components exhibit excellent resistance to thermal shock, exceptional optical clarity, and outstanding chemical inertness, making them ideal for both harsh industrial environments and high-precision optical systems.

The high light transmittance window grade quartz glass offered here combines durability with exceptional optical performance. Whether you require planar substrates, sight glasses, lenses, tubes, or complex custom components, our quartz glass solutions are tailored to meet diverse specifications.

Q&A

Q1: What makes this quartz glass corrosion-resistant?

The extreme chemical purity and network structure of fused quartz make it highly inert to almost all acids and bases, excluding hydrofluoric acid. It outperforms borosilicate and soda-lime glass in chemical resistance, making it ideal for harsh environments.

Q2: Can I request a custom shape or dimension?

Absolutely. We offer custom machining services, including CNC shaping, waterjet cutting, ultrasonic drilling, and thermal forming. Simply submit your drawing or 3D CAD model for a quotation.

Q3: Is this quartz glass suitable for high-temperature applications?

Yes, it can continuously withstand temperatures up to 1,100°C and short-term exposure up to 1,250°C, with excellent resistance to thermal shock.

Q4: Does this quartz glass support UV transmission?

Yes. Our high-purity fused quartz provides excellent transmission in the UV range down to 200 nm, making it ideal for UV curing systems, UV monitoring windows, and spectroscopy.

Q5: How does this compare to borosilicate glass?

Quartz glass offers superior temperature resistance, broader spectral transmission, lower thermal expansion, and better chemical resistance than borosilicate. It is the preferred choice for demanding optical and thermal applications.

Q6: What are the standard lead times?

For in-stock standard shapes, delivery can be made within 3–7 working days. Custom parts typically require 2–4 weeks, depending on complexity and volume.
