FIELD: chemistry.
SUBSTANCE: method for preparation of basic bismuth gallate includes adding with stirring to the bismuth nitrate solution of the water salicylic acid solution at temperature 55°-60°C with molar ratio salicylic acid/bismuth being in the range 0.85-0.99 and process time 1 hour. The obtained basic bismuth gallate precipitate is twice washed with distilled water heated to 60°C, filtered and dried at 60°C.
EFFECT: increased degree of gallic acid use to more than 99,99% and decrease of lead and silver compounds content in the obtained bismuth gallate to 0,001%.
