Product Overview
Quartz glass is a single-component glass of silicon dioxide, categorized into transparent quartz glass and opaque quartz glass (fused silica). Transparent quartz glass offers high optical uniformity and transparency with a SIO2 content above 99.95%, reaching up to 99.999% for high-purity grades. Opaque quartz glass, made from vein quartz or quartz sand, contains over 99.5% SIO2.
Key Characteristics
High Temp Resistance
Softening point of 1730°C. Sustainable use at 1100°C, with short-term peaks up to 1450°C.
Corrosion Resistance
Exceptional chemical stability; 30x better than ceramics and 150x better than stainless steel against acids (except hydrofluoric).
Thermal Stability
Extremely low expansion coefficient. Can withstand rapid cooling from 1100°C to room temperature water without bursting.
Optical Performance
Over 93% visible light transmittance and excellent performance from ultraviolet to infrared spectrums.

Frequently Asked Questions
What is the maximum working temperature for this quartz glass?
The quartz glass can be used continuously at 1100°C, and can withstand short-term exposure up to 1450°C due to its high softening point of 1730°C.
Is the quartz glass resistant to chemical corrosion?
Yes, it has excellent acid resistance (except for hydrofluoric acid), performing 30 times better than ceramics and 150 times better than stainless steel.
What are the primary applications for Model YN-612?
It is widely used in semiconductors, optical communications, electric light sources, laboratory instruments, and various high-temperature industrial environments.
Can quartz glass withstand sudden temperature changes?
Absolutely. It has a very low thermal expansion coefficient and can be moved from 1100°C heat directly into room temperature water without cracking.
