Kurzbeschreibung (Abstract)

The solid state chemistry of nitrides was relatively neglected in the past, compared with the research of the solid state chemistry of oxide compounds, although there has been considerable activity in this area over the past two decades. In contrast to numerous studies on carbon nitride phases initiated by the postulation of a "superhard" C 3N 4 phase, investigations of ternary Si -C-N compounds remain sparse. The compounds Si(NCN) 2 and Si 2C 2(NCN) were the first ternary crystalline phases in the SiCN system synthesized at ambient pressure. The present review highlights recent developments in the synthesis of binary C-N and ternary Si-C-N materials under high pressure and high temperature reaction conditions. The new materials are predicted to exhibit unique properties, such as a high level of hardness, or interesting magnetic and optoelectronic features.
