Abstract

Anthracites are considered as raw materials for the production of fullerenes, and the radiospectroscopy
method is proposed for express diagnostics of carbonic materials. In this work the features of the influence exerted by sizes, forms, and structures of anthracite samples on EPR signals are studied. It has
been demonstrated that the features of the recorded EPR spectra for the coals exhibiting high degrees
of metamorphization are associated with high concentrations of the localized spins at the recording
conditions and also with the peculiarities of their spatial-temporal localization within the fullerene-like
structures of the coals.
