A design for high pressure/high temperature apparatus and reaction cell to achieve SIMILAR 30 GPa pressure in SIMILAR 1 cm volume and SIMILAR 100 GPa pressure in SIMILAR 1 mm volumes and 20-5000 DEG C temperatures in a static regime. The device includes profiled anvils (28) action on a reaction cell (14, 16) containing the material (26) to be processed. The reaction cell includes a heater (18) surrounded by insulating layers and screens. Surrounding the anvils are cylindrical inserts and supporting rings (30-48) whose hardness increases towards the reaction cell. These volumes may be increased considerably if applications require it, making use of presses that have larger loading force capability, larger frames and using larger anvils. L'invention concerne une conception d'un appareil haute pression/haute température et une cellule de réaction destinée à atteindre une pression d' SIMILAR 30 GPa dans un volume d' SIMILAR 1 cm et une pression d' SIMILAR 100 GPa dans un volume d' SIMILAR 1 mm et des températures comprises entre 20 et 5000 DEG C dans un régime statique. Le dispositif comprend des enclumes profilées agissant sur une cellule de réaction contenant le matériau à traiter. La cellule de réaction comprend un appareil générateur de chaleur (18) entouré de couches d'isolation et d'écrans. Des inserts cylindriques et des anneaux de support (30-48) dont la dureté augmente à mesure que l'on s'approche de la cellule de réaction, se trouvent autour des enclumes. Ces volumes peuvent être augmentés de façon considérable si les applications le nécessitent, en utilisant des presses présentant une capacité de charge plus élevée, des cadres et des enclumes plus grands.
