Supercritical fluid synthesis and possible properties of “cubic graphite”
https://doi.org/10.17586/2220-8054-2020-11-4-408-416
Аннотация
We report on supercritical fluid synthesis of an intermediate carbon phase – austite – at a pressure of 180 MPa and temperatures 500–700◦C from soot as a precursor and supercritical carbon dioxide as a solvent. According to the results of electron and X-ray diffractions, spectral measurements and density-functional theory calculations, the observed carbon phase is proved to be cubic with a lattice parameter value of 8.96±0.05 A and a˚ possible structural type as for KFI zeolite.
