FIELD: chemistry.
SUBSTANCE: invention relates to chemistry and can be used for catalysts for obtaining the gases required in the industry and for the synthesis of high-strength ceramics. Method for producing bismuth silicate Bi2SiO5 includes preliminary mechanical mixing of the initial bismuth oxide powders Bi2O3 and silicon oxide SiO2, heating the resulting mixture in a platinum crucible to a predetermined temperature, and mixing the initial powders Bi2O3 and SiO2 carried out directly in the crucible not more than 1 min, and the heating is carried out at 1,020–1,200 °C, then the isothermal holding in molten state in the crucible is carried out for at least 15 minutes, followed by cooling in the furnace together with a crucible with a cooling rate not exceeding 15 °C/min.
EFFECT: technical result consists in obtaining pure Bi2SiO5 while reducing the cost of obtaining it.
