Abstract
We report the temperature dependence of the electrical resistivity of carbon at atmospheric pressure and temperatures up to and above the melting point at 4450±100 K. Vapor-grown graphite fibers of different crystalline perfection were heated with 28-μsec electrical pulses. We also measure the transient reflectivity of graphite irradiated with picosecond laser pulses and find evidence for nonequilibrium heating. We conclude that liquid carbon is metallic with a nearly temperature-independent electrical resistivity of 30±8 μΩ⋅dm.Keywords
