Description

It is proposed a chemical composition and initial components of hollandite matrices for their synthesis with cold pressing and sintering method and it is established the basic regularities of barium titanate-ferrites synthesis with hollandite structure from nanoscale amorphous co-precipitated hydroxocarbonates. It is shown the possibility of effective bonding of cesium and other radionuclide-simulators as a part of barium titanate-ferrites, while cesium loss possibility is excluded or significantly reduced. It is developed optimal conditions and modes of synthesis and the formation of monolithic ceramic materials based on nanoscale powders of barium titanate-ferrites. It is shown that the synthesis temperature is lowered by 300-400 °C, and the heat treatment time is much less compared to the modes of hollandite ceramics synthesis from powders of initial oxides or salts.
