The synthesis of novel materials under high pressures conditions is analyzed through different factors:

- the energy conveyed by pressure compared to that using temperature,

- the thermodynamical effects associated to the specificities of pressure parameter [densification (DV<0), Le Chatelier's rule, the compression of atoms…],

- the chemical effects mainly associated to the enhancement of the reactivity between precursors under high pressures(improvement of the kinetics, improvement of the reactivity at the interface solid/liquid phases, development of reactive pressure…).

This analysis has allowed to develop in the Network D30/003 - through a strong overlap of competences between all involved teams - original research activities mainly focussed on four domains in Materials Chemistry:

- Structural transformations induced by high pressures,

- Synthesis of novel materials,

- Crystal-growth under High pressure,

- Opening of new processes.

In addition a general overview of the scientific activity (2003-2005) and a prospect analysis (2006-2007) shall be given.
