Abstract
The present invention is directed to both stoichiometric and sub-stoichiometric high entropy aluminate spinels as a novel high entropy oxide (HEO) crystal phase. Previously reported HEOs are overwhelmingly stoichiometric structures containing a single cationic site and are stabilized solely by intermixing increasing numbers of cations. According to an aspect of the invention, sub-stoichiometric spinels, containing various mixtures of divalent metal cations and cationic vacancies in nominally equimolar concentration, provide entropic stabilization similarly to cations in stoichiometric spinels. The chromatic, structural, and chemical properties of these complex spinels are highly tunable via incorporation of cationic vacancies and multiple divalent metals, enabling their application as unique pigments, catalysts, and thermal coatings.
