Frequently Asked Questions
Q
What material is this quartz glass made from?
This quartz glass is made from Silicon Dioxide (Natural Quartz), offering a transparent or colorless appearance with no air bubbles or lines on the surface, ensuring excellent optical clarity.
Q
What is the maximum operating temperature for long-term use?
For long-term continuous use, the maximum recommended temperature is 1100 °C. For short-term applications, the material can withstand up to 1300 °C, while thermal processing is performed between 1750 °C and 2050 °C.
Q
What thickness options are available for the quartz glass?
The quartz glass is available in thicknesses ranging from 2 mm to 20 mm, with a circular shape to suit various industrial and optical applications.
Q
What is the thermal expansion coefficient of this quartz glass?
The quartz glass has an exceptionally low thermal expansion coefficient of 5.5 × 10⁻⁷ cm/cm·°C, making it highly resistant to thermal shock and ideal for high-temperature environments where dimensional stability is critical.
Q
What PPM grades are available for purity control?
The quartz glass is available in controlled purity levels of 10 PPM, 20 PPM, and 100 PPM, allowing customers to select the appropriate grade based on their specific application requirements, such as semiconductor manufacturing or optical systems.
Q
How does the compressive strength of quartz glass compare to its flexural strength?
Quartz glass exhibits a very high compressive strength of 1100 MPa, making it extremely resistant to compressive forces. Its flexural (bending) strength is 67 MPa, which is typical for glass materials. For applications involving bending or tensile stresses, appropriate design considerations should be taken into account.
