The working temperature of quartz glass can reach up to 1100 degrees Celsius, with a softening point of 1270 degrees Celsius. Quartz glass is highly resistant to thermal shock, capable of withstanding temperature changes from 1000 degrees Celsius to room temperature.
Quartz glass's high working temperature is due to its extremely low coefficient of thermal expansion, which is about one-fifteenth that of soda-lime glass. This characteristic makes it more suitable for applications requiring high-temperature resistance and stability under temperature variations. The manufacturing process of quartz glass involves melting pure natural quartz crystals with a high SiO2 content, resulting in a material with excellent electrical strength and resistance to thermal shock.
In addition to its high-temperature capabilities, quartz glass is also prized for its high purity, making it suitable for applications in semiconductor manufacturing and other industries where the presence of harmful metals must be minimized. Quartz glass is used in various forms, such as tubes and rods, and is often selected for its ability to withstand extreme temperature conditions and maintain stability in corrosive environments.
