Frequently Asked Questions
Q1
What material is used in the production of this quartz glass product?
The product is made from Silicon Dioxide (Natural Quartz), which ensures high purity, excellent optical clarity, and outstanding thermal resistance. The surface is manufactured to be free of air bubbles and lines.
Q2
What is the maximum operating temperature for long-term and short-term use?
For long-term continuous use, the maximum recommended temperature is 1100 °C. For short-term applications, the product can withstand temperatures up to 1300 °C without compromising structural integrity.
Q3
What thickness options are available for this quartz glass?
The quartz glass is available in a thickness range of 2 MM to 20 MM, making it suitable for a wide variety of industrial, optical, and laboratory applications.
Q4
What PPM grades are available, and why does purity matter?
The product is available in controlled PPM grades of 10, 20, and 100 PPM. Higher purity (lower PPM) is critical for semiconductor manufacturing, optical systems, and precision scientific instruments where contamination must be minimized.
Q5
What is the thermal expansion coefficient and why is it important?
The low thermal expansion coefficient is 5.5 × 10⁻⁷ cm/cm·°C, which is extremely low compared to most materials. This means the quartz glass experiences minimal dimensional change under temperature fluctuations, making it ideal for high-precision and high-temperature applications.
Q6
What is the compressive strength of this quartz glass, and how does it compare to other materials?
This quartz glass has a compressive strength of 1100 MPa, which is exceptionally high. Combined with a Mohs hardness of 5.5 ~ 6.5 and a Young's Modulus of 72,000 MPa, it offers excellent mechanical durability and resistance to deformation under heavy load conditions.
