摘要：
The electrical resistivity of single-crystal Al2O3 was measured at shock pressures in the range 91-220 GPa. Shock pressures were generated by impacts of hypervelocity projectiles accelerated with a two-stage light-gas gun. The resistivity varied from 170 to 20 Ohm cm in the pressure range 91-180 GPa and then rapidly decreased to 0.2 Ohm cm at 220 GPa. (C) 1996 American Institute of Physics.
