FIELD: chemistry.
SUBSTANCE: synthetic diamonds are obtained by decomposition of solid carbonyl compounds of platinum metals in hermetic container at temperature 310°C-800°C during 1-2 hours with ratio of volumes of carbonyl compounds of platinum metals to container volume equal 1:1.1 to 1:100 in neutral atmosphere, further after opening container separation of diamonds from accompanying components is performed by treatment with aqua regia.
EFFECT: increased size of obtained diamonds.
