Resumo
The work is devoted to the experimental study of coronene C24H12 at high pressure and room temperature using in situ X-ray diffraction in a diamond anvil cell. The high-pressure phase P2/m of coronene was found at 0.9 GPa, the PV-equation of state for P2/m coronene phase was defined to 4 GPa: K0 = 10.8(3) GPa, K0′ = 7. At 5.9 GPa partial amorphization of coronene was observed. After the decompression to ambient pressure the high-pressure phase P2/m was preserved, that can be related with partial amorphization.
