Microwave-assisted Sol-gel Synthesis of the MAX Phases Cr2GaC, Cr2GeC, and V2GeC

MAX phases are ternary carbides or nitrides that possess unique material characteristics, often simplified as a mix of metallic and ceramic properties. Many aspects of MAX phases are still being researched, but they have exciting potential applications in high-temperature structural systems, the next generation of nuclear power plants, and concentrated solar power. This project aims to benefit further research into these applications by validating a rapid unconventional synthesis method: microwave-assisted sol-gel synthesis. Three MAX phases (Cr2GaC, Cr2GeC, and V2GeC) were successfully synthesized via this route, which should open the door for more rapid prototyping and ultimately more efficient research.
