“…For the HPHT treatment, we used the profiled-anvil type apparatus [21]. First, we placed a sample covered with tantalum foil into a cylindrical graphite container with graphite caps, and arranged the container into a toroid-shaped lithographic limestone reaction chamber that served as a pressure-transmitting media.…”

A two-stage pressure-and-temperature treatment of the C 60 and C 70 fullerites was carried out. C 60 and C 70 molecules collapsed at the first-stage hot isostatic pressing (220 MPa, argon) and transformed into some fullerene-related form in the 900-1750 O C temperature range. These materials were used at the second stage of the high-pressure-high-temperature (7.7 GPa/1400 O C) treatment to produce the bulk samples that had: a specific weight of about 2.0 g/cm 3 , 40110 GPa Young modulus, 6.012.5 GPa hardness, and elastic recovery above 81 %.Transformations under the treatments were investigated with the X-ray and transmission electron microscopy techniques. The mechanism of the pressure-andtemperature transformations is discussed.Keywords bulk, nanostructured, carbon, hot isostatic pressing (HIP), high pressure high temperature (HPHT)

“…The experiments were carried out using modified "anvils with cavity"-type high-pressure apparatus (Blank et al, 2007). Pressure value was calibrated by electrical resistance jumps in reference metals Ba (5.5 GPa), Bi (2.5, 2.7, 7.7 GPa), Pb (13 GPa) and ZnSe (13.7 GPa) at known phase transitions.…”
