· U6 Si4

U6Si4 is a uranium silicide intermetallic compound belonging to the family of uranium-based ceramics and refractory materials. This material is primarily of research and specialized industrial interest, used in nuclear fuel applications and high-temperature structural applications where uranium's thermal and neutron properties are leveraged. The uranium silicide family is notable for combining high melting points with thermal conductivity suitable for advanced reactor designs, though handling and regulatory considerations limit its adoption compared to conventional uranium oxides or metallic uranium alloys.
