Double Complex Salt [Co(NH3)6][Fe(CN)6] Plasma Treatment

The method of obtaining functional materials almost always influences the physicochemical properties of the resulting substances. The plasma treatment of solid materials is considered to be a more energy efficient method when compared with thermal destruction. Our work is the first to treat double complex salt (DCS) [Co(NH3)6][Fe(CN)6] with different plasma discharge modes. We have demonstrated the possibility of obtaining a single-phase spinel with a CoFe2O4 structure as a result of the calcination in air of the plasma destruction product. The crystallite sizes of the obtained spinel are 40 nm, with a lattice constant 8.38 Å.
