Ceramic materials such as oxides, borides, silicates, and carbides are prominently employed for various applications in high-temperature environments. However, the fast development of new ceramic compositions (e.g. high entropy ceramics) is severely limited by the time-consuming sintering process. Herein, we present an ultrafast high-temperature sintering (UHS) technique for the fabrication of ceramic materials via radiative heating under an inert atmosphere. We employ a carbon-based heater to generate the Joule heat for the fast-sintering method. The ceramic is rapidly heated up to the temperature range of 1,500 - 3,000 K and the heating duration persists from several seconds to minutes depending on the ceramic materials. We have demonstrated how to tune the sintering parameters for different ceramic materials with bulk or coating forms and give examples of high entropy boride composites and ceramics for next-gen thermal barrier coating applications. This strategy can be also applicable to other ultra-high temperature ceramics.
