Liquid carbon density and resistivity

As was shown in Gathers et al (1974 Report UCRL-51644 (Lawrence Livermore Laboratory, September 14)), graphite specimens of low initial densities (heated at gas pressure 2-4 kbar) contract to higher density still in the solid state and then continue further expanding up to the melting line. This eff...

Description
Summary:As was shown in Gathers et al (1974 Report UCRL-51644 (Lawrence Livermore Laboratory, September 14)), graphite specimens of low initial densities (heated at gas pressure 2-4 kbar) contract to higher density still in the solid state and then continue further expanding up to the melting line. This effect was included in the analysis of our experimental results on the fast heating of graphite specimens in thick-walled capillary tubes. At low pressures (up to 4 kbar) the liquid carbon density γ∼1.2 g cm(-3). In that case the resistivity of liquid carbon ρ∼2200 µΩ cm. Liquid carbon under high pressures (P≥50 kbar) has a high density (γ≥1.8 g cm(-3)), and the resistivity equals ∼600-730 µΩ cm.
