Shock Compressibility of Single-Crystal Silicon in the Pressure Range 280–510 GPa

The shock compressibility of single-crystal silicon is experimentally studied in the pressure range of 280 to 510 GPa. Shock waves are created using Mach’s explosive cumulative generators. The parameters of shock waves are determined by the impedance matching method, and single-crystal quartz is used as a ref-erence substance. The results agree well with the ab initio calculation results and with the data obtained using laser shock waves.
