Experimental modeling of natural carbide-involving reactions, implicated in the graphite and diamond formation and estimation of the iron carbide stability in the presence of S-bearing fluids, sulfide melts as well as mantle silicates and oxides, was performed using a multi-anvil high-pressure split-sphere apparatus. Experiments were carried out in the carbide-sulfur (Fe3C-S), carbide-sulfur-oxide...
Experiments on the synthesis of inclusions-bearing diamond were performed in the SiO2–((Mg,Ca)CO3–(Fe,Ni)S system at 6.3GPa and 1650–1750°C, using a multi-anvil high pressure apparatus of the “split-sphere” type. Diamond synthesis was realized in the “sandwich-type” experiments, where the carbonate–oxide mixture acted as a source of both CO2-dominated fluid and carbonate–silicate melt, and Fe,Ni-sulfide...
Experimental simulation of the interaction of wüstite with a CO2-rich fluid and a carbonate-silicate melt was performed using a multianvil high-pressure split-sphere apparatus in the FeO-MgO-CaO-SiO2-Al2O3-CO2 system at a pressure of 6.3GPa and temperatures in the range of 1150°C–1650°C and with run time of 20h. At relatively low temperatures, decarbonation reactions occur in the system to form iron-rich...
Diamond crystallization from the tin–carbon system has been studied at 7GPa and temperatures ranging from 1600 to 1900°C with reaction times from 1 to 20h. Both diamond growth on the seed crystals and diamond spontaneous nucleation were established, providing evidence for the catalytic ability of tin. A distinctive feature of the Sn–C system is the existence of a significant induction period preceding...
