Quartz tubes are a special type of industrial technical glass made from silicon dioxide (SiO2), boasting a range of excellent physical and chemical properties. Below are some main applications and characteristics of quartz tubes:
High temperature resistance: The softening point temperature of the quartz tube is approximately 1730°C, it can be used for a long time at 1100°C, and short-term high temperature use can reach up to 1450°C.
Corrosion-resistant: Quartz tubes hardly react chemically with other acidic substances, boasting high acid resistance.
High thermal stability: The quartz tube has a low thermal expansion coefficient, enabling it to withstand drastic temperature changes. It will not shatter even when cooled rapidly under high temperatures.
Transmittance: The quartz tube exhibits excellent transmittance across the entire spectrum from ultraviolet to infrared, with visible light transmittance exceeding 93%. Particularly in the ultraviolet spectrum, the transmittance reaches over 80%.
Electrical Insulation Property: The quartz tube has a very high resistivity, making it an excellent electrical insulator, and it maintains good insulation properties even at high temperatures.
Fragile: Although quartz tubes have many advantages, they also have the drawback of being fragile.
Application Fields: Quartz tubes are extensively used in various fields such as electrical lighting, semiconductor, optical communication, metallurgy, construction materials, chemistry, machinery, power, and environmental protection.
Special Applications: Quartz tubes are also used in electric hot tubs, electric fireplaces, electric heaters, and other heating equipment. They are particularly suitable for scientific research laboratories, pollution-free environments, and corrosive heating conditions involving acids and alkalis.
Deep Processing: Deep-processed quartz tubes require no coating, offering benefits such as stable emissivity, non-deformation at high temperatures, no harmful radiation, and no environmental pollution.
Heating Element: Quartz tubes, as heating elements, feature high electrical to thermal conversion efficiency, rapid heating, and low thermal inertia. They are suitable for various industries requiring heating, such as dyeing, shoe manufacturing, painting, food processing, electronics, textiles, wood, paper, automotive, plastics, furniture, metals, heat treatment, packaging machinery, and more.
Quartz tubes, due to their unique physical and chemical properties, are widely used in industrial and scientific research fields.
