Uniform, ultrahigh-temperature, stable plasma apparatus
Category: Other
Developers: Yale University
Product Description:The team developed a uniform, ultrahigh-temperature, stable plasma (USP) apparatus using tip-enhanced carbon-felt electrodes (Patent: PCT/US2023/034378). It generates large-volume, controllable plasma with temperatures up to 8,000 K, high spatial uniformity and temporal stability enabling rapid synthesis and surface modification of refractory alloys, advanced ceramics and composites in seconds. Because its USP product relies on radiative and tip-mediated discharge from carbon-felt electrodes, high-temperature exposure in an oxidization environment may induce minor carbothermal reduction or carbon contamination of oxygen-sensitive materials. Nonetheless, the ultrashort dwell times (seconds) for rapid materials synthesis minimize these side reactions, and ongoing development aims to eliminate the potentially adverse carbon contamination and to extend uniform heating to larger volumes.
