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.).
