The material supports a long-term use temperature of up to 1100°C, and can withstand short-term exposure up to 1300°C. Its thermal processing temperature ranges between 1750°C and 2050°C.
It features a high compressive strength of 1100Mpa, a flexural strength of 67Mpa, and a Mohs hardness rating of 5.5 to 6.5, making it highly durable under mechanical stress.
This quartz material has an extremely low thermal expansion coefficient of 5.5*10-7 cm/cm.°C, which provides excellent resistance to thermal shock.
The material is available in a circular shape with a thickness range from 2mm to 20mm. The surface is highly refined with no air bubbles and no lines.
The PPM grade of this natural quartz material is strictly controlled at 10/20/100PPM levels to ensure high chemical purity and performance integrity.
