The electrical conductivity of Al2O3 under shock-compression
Sapphire (Al2O3) crystals are used below 100 GPa as anvils and windows in dynamic-compression experiments because of their transparency and high density. Above 100 GPa shock pressures, sapphire becomes opaque and electrically conducting because of shock-induced defects. Such effects prevent temperature and dc conductivity measurements of materials compressed quasi-isentropically. Opacities and ...
متن کاملElectrical Conductivity of Chemically Reduced Graphene Powders under Compression
Carbon materials such as graphite and graphene exhibit high electrical conductivity. We examined the electrical conductivity of synthetic and natural graphene powders after the chemical reduction of synthetic and natural graphite oxide from synthetic and natural graphite. The trend of electrical conductivity of both graphene (synthetic and natural) was compared with different graphite materials...
متن کاملA first-principle investigation of antigorite up to 30 GPa: Structural behavior under compression
The structure of antigorite (m = 17) has been studied by density functional theory from 0 to 30 GPa. The fourth-order Birch-Murnaghan equation of state fit of the thermally corrected LDA results yields an equilibrium volume (V0 = 2853.13 Å3), bulk modulus (K0 = 64.6 GPa), and its pressure derivative (K0′ = 6.94) in good agreement with experimental results. Two changes in compression mechanism o...

متن کاملElectrical and optical measurements on fused quartz under shock compression
The resistivities of specimens of Si02 (fused quartz) singly and doubly shocked in the i0 to 45 and 27 to 90 GPa range, respectively, demonstrate a marked decrease from values of ~10~'m to ~0.1~'m at single shock pressure of ~40 and double shock pressure of ~74 GPa. The shock-induced polarization profiles also show a sudden change of electrical properties of the material at those pressures. The...
