Product Overview: Precision rectangle quartz glass tubing is a specialized industrial glass made from high-purity silicon dioxide (SiO₂). It serves as an exceptional foundational material due to its superior physical and chemical properties. This quartz glass tubing is widely used in electric heating devices, such as electric heaters, to generate heat.
Key Features:
High-Temperature Resistance: Quartz glass has a softening point of approximately 1730°C. It can withstand long-term use at temperatures up to 1100°C and short-term exposure to temperatures as high as 1450°C without deforming or breaking down.
Outstanding Corrosion Resistance: Quartz glass is nearly impervious to chemical reactions with most acids, except hydrofluoric acid. Its corrosion resistance is 30 times higher than ceramics and 150 times greater than stainless steel. The chemical stability of quartz glass, especially at high temperatures, surpasses all other engineering materials.
Exceptional Thermal Stability: With an extremely low coefficient of thermal expansion, quartz glass can endure rapid temperature fluctuations. Even when heated to around 1100°C and then rapidly cooled in room-temperature water, it will not crack or shatter.
Superior Light Transmission: Quartz glass boasts excellent light transmission properties across the entire spectrum from ultraviolet (UV) to infrared (IR) wavelengths. It has a visible light transmission rate of over 93%, with UV light transmission exceeding 80%, making it ideal for applications requiring high optical clarity.
Excellent Electrical Insulation: Quartz glass provides excellent electrical insulation, with resistance values 10,000 times higher than ordinary glass. It remains a superb insulating material even under high-temperature conditions, making it suitable for electrical and electronic applications.
Applications: Due to its outstanding physical and chemical properties, precision rectangle quartz glass tubing is widely used in industries such as:
Electric heating devices (heaters, stoves) Semiconductor manufacturing Optical communication Military and defense Metallurgy Construction materials Chemical processing Mechanical engineering Power generation Environmental protection Note: While quartz glass tubing has numerous advantages, one limitation is its fragility, which makes it prone to breaking under mechanical stress.
Conclusion: Precision rectangle quartz glass tubing is a versatile, high-performance material suited for demanding applications that require extreme temperature resistance, corrosion resistance, and excellent optical and electrical insulation properties.
