Abstract
Properties of impact diamonds from the Popigai Deposit have been studied in a free state and in a composition of a compact. Raman spectra have been taken of the initial micron powders and polycrystals HP-HT sintered both in the presence of sintering aids and without them. Hardness, H V , of sintered polycrystals have been found, structural variations in diamond crystal lattice depending on the sintering conditions have been studied.
