【Abstract】 The experimental data of Hugoniot equation of state are provided for calcite (with the initial density 2.714 g/cm3) over a pressure range of approximately 0.35-1.41GPa. The experiment was conducted on a single-stage light-gas gun of 57mm. The reverse ballistic experimental configuration and the normal ballistic experimental configuration in combination with the electro-magnetic particle velocity gages and a set of analysis techniques were used in the experiment to understand the Hugoniot properties of calcite. On the experimental pressure range, the obtained linear relation between the shock velocity D and the particle velocity u of calcite.更多还原
