FY19 ANNUAL REPORT
Gram scale synthesis route for high entropy oxides, with chemical control over particle composition and size. Sandia researchers, Stanley Chou and Beth Paisley, developed a gram scale synthesis route for high entropy oxides, with chemical control over particle composition and size. Since high entropy materials are stabilized by configurational entropy, increasing the number of elements in the system creates stability and allows for unique combinations of atoms within one material. These materials
are tailorable in composition and fabrication method, allowing for mechanical and thermal response design considerations. The specific material created has the potential for enhancing radiation insult resilience and fault tolerance with a coating that can be applied during part fabrication, or as a coating added to existing or COTS parts. The ability to synthesize ceramics as designed will serve as a materials discovery building block for several of the Labs’ mission areas.
