Frequently Asked Questions
Q What is the maximum operating temperature for quartz glass?
Quartz glass can withstand a short-term use temperature of up to 1300 °C and a long-term continuous use temperature of up to 1100 °C. Its thermal processing range is 1750–2050 °C, making it suitable for high-temperature industrial applications.
Q What material is this quartz glass made from?
This quartz glass is made from Silicon Dioxide (SiO₂) derived from natural quartz. It is transparent or colorless, with a surface free of air bubbles and lines, ensuring excellent optical clarity and purity.
Q What thickness options are available for quartz glass?
Quartz glass is available in thicknesses ranging from 2 mm to 20 mm in a circular shape. Custom thickness requirements within this range can be accommodated based on specific application needs.
Q What PPM purity grades are available?
Quartz glass is offered in controlled purity grades of 10 PPM, 20 PPM, and 100 PPM. This allows customers to select the appropriate purity level depending on the sensitivity of their application, such as semiconductor manufacturing or optical instrumentation.
Q Why is the low thermal expansion coefficient important for quartz glass?
The extremely low thermal expansion coefficient of 5.5 × 10⁻⁷ cm/cm·°C means quartz glass expands very minimally when exposed to heat. This property makes it highly resistant to thermal shock, allowing it to withstand rapid temperature changes without cracking or deforming — a critical advantage in laboratory and industrial environments.
Q What is the compressive strength and hardness of quartz glass?
Quartz glass has an impressive compressive strength of 1100 MPa, making it highly resistant to mechanical pressure. Its Mohs hardness rating of 5.5–6.5 indicates good surface durability, suitable for applications requiring both structural integrity and resistance to surface scratching.
