So  Alumina ceramic tube  is commonly used in high-temperature furnaces, thermocouples tubes, insulating tubes, and corona electrode’s square ceramic tubes. In this articles, we would like to discuss how to use alumina ceramic tubes at high temperatures to ensure optimal performance and longevity. 1. Proper handling and storage Alumina tubes are brittle, avoid any sudden impacts or shakes to prevent breakage. During storage, it should be stored in a dry and clean environment to prevent contamination. 2. Preheating When using alumina tubes, we should be preheated gradually, the heating rate should be controlled at 5 degrees per minute until it reaches the desired temperature, the slower the better. 3. Cl...

The Application of Alumina and SiC Porous Ceramics

Source: https://www.innovacera.com/news/alumina-and-sic-porous-ceramics.html Application: Semiconductor wafer processing, laser numerical control processing, PCB, flexible screen, precision grinder, air floating platform, air bearing, optical components. 1) The smaller the pore size, the greater the resistance and the greater the degree of vacuum required, but the greater the suction power obtained. 2) The maximum use temperature of alumina/silicon carbide microporous ceramics is about 1000 ° C, and the maximum use temperature is also related to size and shape. Still, if glue is stuck, it can only be lower than 100 ° C. 3) Microporous ceramics generally do not mention the roughness problem, because there are micropores, but the surface smoothness is similar to Ra0.8 of dense ceramics. 4) Low thermal conductivity. Only dense materials will have high thermal conductivity. 5) Microporous ceramics cannot be used in a humid environment or come into contact with conductive liquids. Otherwi...
