Ceramic tubes are primarily used in high-temperature applications, particularly in furnaces and kilns, due to their excellent thermal properties and resistance to extreme conditions. They serve various functions such as supporting heating elements, providing lead outs for electrical cables, and facilitating temperature measurement or burner holes in gas and oil-fired kilns.
Supporting Heating Elements: Porous ceramic tubes are used to support wound elements in larger furnaces and kilns. This application leverages the ceramic tubes' ability to withstand high temperatures and thermal shocks, ensuring stable support for the heating elements.
Electrical Lead Outs: Ceramic tubes are ideal for providing lead outs for electrical cables in high-temperature environments. Their dielectric properties and gas-tight nature ensure a protective environment, especially when used at extremely high temperatures. This makes them suitable for applications where electrical insulation and protection are crucial.
Temperature Measurement and Burner Holes: Ceramic tubes are used for temperature measurement and as burner holes in kilns. Their ability to resist corrosion and maintain structural integrity at high temperatures makes them suitable for these critical roles. Custom ceramic burner components, available in materials like alumina or silicon carbide, are also supplied for specific applications.
Customization and Manufacturing: Ceramic tubes can be custom-designed with special dimensions and tolerances to meet specific requirements. Manufacturers offer capabilities to add features such as flanges, drill holes, and cut slots in various standard materials. This customization ensures that the tubes can be adapted to a wide range of industrial needs.
Material Specifics: Alumina ceramic tubes, with high purity rates, are noted for their low thermal expansion, superior thermal conductivity, and high compression resistance. These properties make them thermal shock resistant and suitable for use in environments where extreme temperature stability is required, up to 1800°C. Other materials like quartz, mullite, corundum, sillimanite, mullite-bonded silicon carbide, recrystallised silicon carbide, and zirconia are also used, each offering specific benefits depending on the application's temperature and environmental demands.
Common Uses in Industries: Ceramic tubes are used in various industries for applications such as semiconductors and battery production, thermocouples and mineral-insulated cables, vacuum brazing and heat treatment, vacuum curing and sintering, and testing in water, waste, soil, aerospace ceramics and metals, oil and gas, and solid oxide fuel cells. They are also used in the production of polymer composites and graphene.
In summary, ceramic tubes are versatile and essential components in many high-temperature industrial processes, leveraging their unique thermal and mechanical properties to support a wide range of applications.
