Equation of State and Transport Data for Initially Wide Band Gap Materials from 0.1 to 10 Mbar*

We present a suite of new shock compression data (pressure, temperature, density and reflectance) on originally large band-gap fluids including CO2 and Kr from 0.1 to 10 Mbar. Initial densities and pressures for these samples are tuned using diamond anvil cell containers. Shock data starting from initial cryogenic-liquid densities show insulator to conductor transitions at shock pressures less than 1 Mbar for Kr and near 2 Mbar for CO2. By comparing shock data at different initial densities we estimate the specific heat over the pressure range where significant ionization occurs.
