FIELD: glass.
SUBSTANCE: invention relates to production of oxide glassy materials having ferromagnetic properties, which can be used as matrices for introducing ferroelectrics to obtain multiferroics. Initial iron-containing silicate glass of composition 15K2O-20Fe2O3-65SiO2 mol. % is synthesized by way of boiling in electric furnace, cast on steel mould, then it is annealed at 550 °C for 2 hours. Crystalline phase of magnetite - Fe3O4 is formed in the process of synthesis in hardened and annealed glass. Glass is subjected to ion exchange between alkali glass cations and cations of molten salt of sodium nitrate and lithium nitrate, resulting in formation of pores.
EFFECT: technical result of invention is simplification of method of producing porous glass with magnetic phase.
