Description
Summary:In recent years, a lot of work has been focused on the synthesis of novel carbon nitrides, especially crystalline C 3N 4 phases. Numerous attempts to synthesise the theoretically predicted solids have been published. This review summarises the theoretical work as well as the attempts to prepare carbon(IV) nitrides by chemical and physical vapour deposition, and in particular on the concepts and results of bulk synthesis routes. Although very interesting materials have been obtained, a comprehensive characterisation of a crystalline C 3N 4 phase is still missing. In 1999, a novel class of nitrides, which posses the spinel structure, has been discovered. The synthesis and properties of the high pressure phases γ-M 3N 4 with M = Si, Ge and the first tin nitride γ-Sn 3N 4 are reviewed. Related oxide nitride spinel compounds, other ternary phases such as Si/C/N as well as subnitrides, sialons and amorphous phases are mentioned briefly.
