During previous reporting periods we studied properties of iodine doped FCC in comparison with activated carbon. An additional goal was to investigate the possibility to convert iodine doped FCC and activated carbon into ceramic-like material avoiding iodine loss. In order to obtain ceramic based on CxNy with fullerene structure we decided to carry out gamma irradiation of iodine doped samples in nitrogen atmosphere (0.7 atm. N2). It was found that iodine doping and irradiation caused principal changes in composition of FCC such as substituting of fullerene C60 and graphite (both formed by benzene-like carbon rings) for crystalline chaoite phase (formed by carbyne carbon chains). It was assumed that iodine doping of activated carbon, which does not contain significant amount of crystalline phases, also causes formation of carbon chains.
During current reporting period the experiments on irradiation were completed and the results obtained were summarized. The experiments on synthesis of another ceramic-like material by conversion of iodine-doped FCC and activated carbon to SixCy have been continued.
