Allotropes of carbon based materials, such as graphite, fullerenes and nanotubes, and diamond are currently a focus of great interest. New diamond (n-diamond) has been proposed as a new carbon allotrope; its electron diffraction pattern matches that of cubic (Fd3 m) diamond apart from some additional reflections that are forbidden for diamond, indexed as {200}, {222} and {420}. n-Diamond has been found experimentally for more than 10 years, yet its structure and stability are not unambiguously resolved, and some controversies still exist. A comprehensive review of recent developments in the experimental and theoretical knowledge of n-diamond is presented. Synthesis methods reported for n-diamond and transformation mechanisms from other carbon allotropes are discussed. The various crystal structure models proposed for n-diamond are summarised and critically assessed. The stability to aging and other properties of n-diamond are briefly considered. Finally, the potential for technological application of n-diamond as an electromagnetic absorber is discussed.

“…Efforts to extend the pressure range by adopting sintered diamond anvils are in pro gress. To date, pressures as high as 60 GPa at room temperature have been achieved [Endo et al, 1987], and high-temperature experi ments within this pressure range are now be ing attempted.…”

Around the world there are many high‐pressure devices coupled to synchrotron radiation sources. Of these facilities, MAX80 (for multianvil high‐pressure X ray system) at the Photon Factory (the synchrotron radiation laboratory at the National Laboratory for High‐Energy Physics in Tsukuba, Japan ) has a unique capability for experiments that are simultaneously high pressure and high temperature. Because of MAX80's large sample chamber, a resistance heater can be installed so that the specimen can be heated uniformly to 1600°C at pressure. Scientists have employed this apparatus for in situ X ray observations of phase transitions, measurements of silicate melts, and other high‐pressure experiments.
