Interaction in fullerene—ammonia system at 423—773 K

The interaction of C₆₀ fullerite and C₆₀—NH₄Cl mixture (8 wt. % of NH₄Cl, promoter of reaction) with ammonia was investigated at a starting NH₃ pressure of 0.6—0.7 MPa in the temperature range 423—773 K. Raising the temperature to 723 K is accompanied by hydrogenation and nitrogenation of the C₆₀ matrix. Treatment of fullerite with ammonia at 773 K is followed by the decomposition of the fullerene framework and formation of X-ray amorphous product. The physico-chemical properties of hydride-nitride phases formed during the interaction were investigated. Published in Russian in Izvestiya Akademii Nauk.
