Alumina Ceramic Rods / Aluminum Oxide Insulation Rods for Battery
1. Description:
Technical ceramics have been used for various parts of the engine for the past 30-40 years, but a lot of activity currently surrounds the development of silicon carbide (SiC/SiC composites) for use in jet engine turbines, mainly concentrated on the turbine blades. The main driver is fuel efficiency, as engineers seek to run the jet engine without the need for cooling channels that currently stop the metal alloy blades from melting. If the blades were made of ceramic composites, which could deal with temperatures of 1,500-1,600°C, the engine could run at higher temperatures. Energy efficiency would therefore increase, which leads to less fuel and the airplane’s ability to fly further or more efficiently.
