The round transparent quartz plate is made of high-purity fused silica (SiO ⊃2;), which has excellent optical properties, high temperature resistance and chemical stability. The product has a wide range of diameters (8-500mm) and thicknesses can be customized according to needs (0.1mm to 50mm), suitable for high-precision optics, semiconductors, laser technology and other fields.

Frequently Asked Questions (FAQ)

Q1: What sizes and thicknesses can you customize for your circular quartz plates?

A1: We offer circular quartz plates in a full range of diameters from 8 mm to 500 mm. In terms of thickness, we typically provide standard specifications ranging from 1 mm to 50 mm, and we fully support in-depth customization of non-standard sizes and special thicknesses based on customer drawings.

Q2: How does this quartz plate perform in terms of optical transmittance?

A2: Our transparent quartz plates have extremely high transmittance in the visible light spectrum, typically reaching over 93%. At the same time, they exhibit excellent light transmission across the entire spectrum from ultraviolet to infrared, meeting the requirements of various precision optical instruments.

Q3: Can the product withstand extreme temperature changes?

A3: Absolutely. Quartz plates have an extremely low coefficient of thermal expansion and excellent thermal stability. They can withstand extreme temperature changes; even after prolonged use at 1100°C or when transferred directly from high temperatures into room-temperature water, they will not shatter.

Quartz plate has the following core characteristics:

- High light transmittance: UV to IR band (170nm-2500nm) transmittance > 90%, suitable for wide spectral applications.

- High temperature resistance: softening point up to 1730 ° C, can work stably for a long time at 1000 ° C.

- Low coefficient of thermal expansion: 5.5 × 10 ° C/℃, excellent thermal shock resistance, suitable for environments with severe temperature changes.

- Chemical inertness: resistant to strong acids (except hydrofluoric acid), alkali and organic solvent corrosion, suitable for harsh chemical environments.

- High hardness: Mohs hardness level 7, scratch resistance, high mechanical strength.
