The structure of metal-carbon nanocomposites obtained by pyrolysed yttrium diphthalocyanine derivatives was established by transmission electron microscopy and atomic force microscopy. It is shown that during high-temperature pyrolysis α-yttrium crystals forms a wide-range network of nanoclusters in a graphitized carbon matrix on a scale of tens of micrometers. The features of structuring studied on a model object are common for radioactive isotopes of lanthanides and actinides, which creates the scientific basis for using metal-carbon nanocomposites as matrices for immobilization of high-level waste from spent nuclear fuel.
