Abstract
Nitrides constitute an important class of materials due to their physical properties. In this way, all processes related to their synthesis or shaping are of relevant interest. A solvothermal process can be described as a reaction between precursors in a close system in the presence of a solvent and at a temperature higher than the boiling point of the solvent, with pressure being consequently involved. Depending on the pressure and temperature, the solvent is in sub- or supercritical conditions. The system precursors/solvent can be either homogeneous or heterogeneous. Concerning nitrides, solvothermal processes have been mainly developed in three domains:
1. | the preparation of novel compositions | ||||
2. | the elaboration of nanocrystallites well defined in size and morphology | ||||
3. | the crystal-growth of functional nitrides such as GaN. |
