Abstract
Granular superconductivity in powders of small graphite grains (several tens of micrometers) is demonstrated after treatment with pure water. Thetemperature, magnetic field and time dependence of the magnetic moment of the treated graphite powder provides evidence for the existence of superconducting vortices with some similarities to high-temperature granular superconducting oxides but even at temperatures above 300 K. Roomtemperature superconductivity in doped graphite or at its interfaces appears to be possible.
