Abstract: 
Liquid phase technologies for high-grade ceramic oxide powders of technical purpose and methods of their modification have been developed. On the basis of physico-chemical research methods various mechanisms of modifying processes have been analyzed. Substitution of the main ions by doping ones occurs in complex oxide powders followed by the formation of solid solutions. A powder which was obtained via TiO2 modification by sulfur has a surface layer in which sulfur forms chemical bonds.
