Anomalous behavior in the crystallization of diamond and graphite H. M. Strong and R. E. Hanneman, "Crystal Growth" [Pergamon] 579-83 (1967) : Diamond Synthesis Anomalous behavior in the crystallization of diamond and graphite H. M. Strong and R. E. Hanneman, "Crystal Growth" [Pergamon]...
Crystallization of diamond was studied in the CO 2–C, CO 2–H 2O–C, H 2O–C, and CH 4–H 2–C systems at 5.7 GPa and 1200–1420°C. Thermodynamic calculations show generation of CO 2, CO 2–H 2O, H 2O and CH 4–H 2 fluids in experiments with graphite and silver ...
Simultaneous crystallization of diamond and cubic boron nitride from the graphite relative BC2N under high pressure/high temperature conditions. Chem Mater. 1993; 8 :5.T.Sasaki,M. Akaishi,S. Yamaoka,et al.Simultaneous Crystallization of Diamond and Cubic Boron Nitride from the Graphite Relative BC...
We experimentally studied the crystallization of diamond and silicate phases from the starting composition Fe0.36Ni0.64 + silicate glass + graphite and calculated the Fe mole fractions of the silicate phases crystallizing under these conditions. The silicates synthesized together with diamond had low Fe ...
The making of a material is a process that often involves phase transformations. How a material transforms from one stable phase to another has wide-spread consequences: for technological applications such as metal alloys1, colloids2,3,4 and the graphite-diamond transition of carbon5; but also ...
Transparent crystalline yttrium aluminum garnet (YAG; Y3Al5O12) is a dominant host material used in phosphors, scintillators, and solid state lasers. However, YAG single crystals and transparent ceramics face several technological limitations including c
EXPERIMENTAL STUDIES OF DIAMOND CRYSTALLIZATION ZONES IN A RECESSED ANVIL-TYPE HIGH PRESSURE APPARATUS In this paper we discuss experiments on diamond synthesis in a recessed anvil-type high pressure apparatus with a uniform accommodation of powdered reaction components (a graphite powder and particles ...

Using a previously developed algorithm for the computer generation of realistic random network models of a-Si, we have investigated the topological conditions that lead to crystallization. We find that a single atom whose local environment has the same topology as the diamond structure may serve as...
