Abstract
Additional experimental studies of shock compressibility of pressed Ceylon graphite and also of its dynamic compressibility in a mixture with fluoropl ast at pressures P = 10-40 GPa are carried out. These new results were comp ared with recent data and notions suggested by other authors which stimulat ed recourse to our previous experimental dependences of the electric conduc tivity of thin plates cut from monolith natural Ceylon graphite and placed in dielectric media with dynamic properties similar to those of graphite on the pressure in the dielectric behind the front of a plane Ii-shaped shock wave and on the duration of graphite pressurization. Using experimental re cords and one of the modern models of a conductor - insulator mixture we de rived an analytical dependence of the concentration of diamond-like modific ations on the duration of graphite pressurization at various loading pressu res and plotted curves of dynamic graphite compressibility that also depend ed on pressurization time.
