It is shown that the temperature dependence of the value of energy gap in superconductors is characteristic for the order–disorder transition. The obtained relationship between the critical parameters of the Bose–Einstein condensate of electrically charged particles is in accordance with measurement data of superconductor critical parameters. The dependence of the critical temperatures for both – I and II – type superconductors and their Sommerfeld constants (and their Fermi energies) is obtained. It is marked that among the high-temperature superconducting ceramics there are the both – I and II – type superconductors. In total the phenomenon of superconductivity is seen as a consequence of ordering into the zero-point oscillation system of the electron gas in a metal at low temperatures. The obtained estimations of the interaction of zero-point oscillations are in satisfactory agreement with the data measurements of critical parameters of I and II type superconductors.
Research highlights
► The effect of superconductivity is considered as a consequence of an ordering of the electron gas zero-point oscillations.
► In this way, the main critical parameters of superconductors of both – I and II – type were calculated and satisfactory agreement with measurement data was obtained.
