Abstract :
The process of producing finely dispersed Ba1-xSrxTiO3, BaTiO3 and (Bi1-xLax)4Ti3O12 powders with ultra-and nanosized particles by chemical reactions in multi-component salt melts is developed. Also the opportunities of sol-gel method for the film structures formation are used by means of ferroelectric powders inclusion in an oxide silicate matrix. The optimal syntheses condition of film glass-ceramical structures formation are determined.
