Bakul Institute of superhard material of the National Academy of Sciences of Ukraine popup.description1 Study of the process of growing diamonds at pressures up to 10 GPa and temperatures up to 1800°C in hydrocarbon growth systems such as saturated and unsaturated hydrocarbon compounds, polycyclic aromatic hydrocarbons, polyethylenes and diamondoids (diamondoids). The conditions of diamond formation when using different types and compositions of growth media will be determined, the features of nucleation and growth kinetics of the diamond phase will be investigated, the features of the formation of the defect-impurity composition of crystals and their crystal structure depending on the growth conditions will be formulated, and the initial data will be formulated for the development of technological foundations for the use of hydrocarbon media to obtain high-purity structurally perfect diamonds. popup.nrat_date 2025-01-07 Close
