Our transparent quartz plate is made of high-purity fused silica (SiO ₂ ≥ 99.99%), which has excellent high temperature resistance, low coefficient of thermal expansion, high transmittance and excellent chemical stability. The product diameter range covers 5mm to 1800mm, and the thickness can be customized according to needs (0.1mm to 50mm), suitable for precision optics, semiconductors, photovoltaics, laser technology, and high-temperature industries.

FAQ: Frequently Asked Questions

Q: What are the maximum processing dimensions for transparent quartz plates? Can you produce non-standard shapes?

A: Our transparent quartz plates can be custom-made with diameters ranging from 5 mm to 1,800 mm, and thicknesses can be flexibly adjusted from 0.1 mm to 500 mm. In addition to standard circular and rectangular shapes, we support customization based on your drawings or samples. We can process complex shapes such as stepped plates, irregularly shaped plates, slotted plates, and drilled plates, providing fully personalized production tailored to your specific application.

Q: Will the product shatter or deform under high-temperature and high-pressure conditions?

A: Quartz glass has an extremely low coefficient of thermal expansion (approximately 5.5×10⁻⁷/°C) and excellent thermal stability. For example, even if a quartz plate is heated to 1100°C and then immediately immersed in cold water, it will not shatter. This allows it to maintain structural integrity and dimensional accuracy in environments with extreme temperature fluctuations.

Q: What levels of light transmittance and purity can the material achieve?

A: We use Donghai Grade 1 crystal material with a SiO₂ purity of over 99.99%. In terms of optical performance, visible light transmittance exceeds 93%, and transmittance in the ultraviolet range (200–250 nm) can reach over 80%, meeting the requirements for a wide spectrum of applications ranging from deep ultraviolet to near-infrared.

Q: How does the product perform in terms of weather resistance in corrosive environments?

A: With the exception of hydrofluoric acid and hot phosphoric acid, quartz glass reacts very little with acids, alkalis, or salts. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel, making it an ideal window material for highly corrosive environments such as chemical processing and metallurgy.
