Abstract
The results of comparative studies of thermal decomposition of hexa-aqueous cobalt(II) nitrate and Zr-Si
oxide matrix with impregnated hexa-aqueous cobalt(II) nitrate from its aqueous solution are given. It has been
shown that the interaction of aqueous solution of cobalt(II) nitrate with the Zr-Si oxide system occurs with the
formation of hydroxide-oxide structures of cobalt at low (110-120 oC) and cobalt oxide Co3O4 mainly at
elevated (>150 оC) temperatures. It was established almost a uniform distribution of cobalt according to the
X-ray fluorescence microscopy data.
