Peculiarities of diamonds formed in alkaline carbonate‐carbon melts at pressures of 8–10 GPA: Scanning electron microscopy and cathodoluminescence data

Abstract: Summary: Diamond crystallization with both spontaneous and seeded nucleation was realized in the system Na 2 Mg(CO 3 ) 2 -K 2 Mg(CO 3 ) 2 -C (graphite) at 8-10 GPa and 1700-1800 o C. The crystallization products were transparent colorless diamond single crystals of octahedral habit up to 100-150 µm in size. Scanning electron microscopy (SEM) showed that the growing diamond material was precipitated on both octahedral {111} and cubic {100} faces of synthetic and natural diamond seed crystals by layers of octahe… Show more

“…Laboratory experiments carried out in the last 13 yr have established the role of carbonates (Akaishi et al, 1990;Litvin et al, 1998;Litvin et al, 1999) and carbonate ϩ water (Pal'yanov et al, 1999a,b;Akaishi and Yamaoka, 2000;Sokol et al, 2001) as catalysts for diamond nucleation and growth (with graphite as the carbon source). In fact, carbonate ϩ water allow diamond synthesis under the P-T conditions that correspond to natural diamond formation (Pal'yanov et al, 1999b).…”
