Solvothermal synthesis of nitrides as fine particles

Abstract

The preparation of fine particles well defined in size and morphology is an important challenge for: Nitrides are now largely involved in many applications. In order to control the composition and particles-size of such divided nitrides a new elaboration process, the solvothermal synthesis, using nitriding solvents liquid (NH₃ and NH₂NH₂) in high pressure-high temperature conditions has been set-up. (i) a better understanding of divided materials, in particular the surface effect on physical properties, (ii) different applications (ceramics, heterogeneous catalysis.).
