Post-spinel-type ABO compounds are stable at higher pressures than spinel phases. These compounds have garnered much interest in geo- and materials science for their geochemical importance as well as potential application as high ionic conductors and materials with strongly correlated electrons. Here, large-volume high-pressure syntheses, structural features and properties of post-spinels are reviewed. Prospects are discussed for future searches for post-spinel-type phases by applying advanced large-volume high-pressure technology.
