The electrical resistivity of single-crystal Al{sub 2}O{sub 3} was measured at shock pressures in the range 91{endash}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 {Omega} cm in the pressure range 91{endash}180 GPa and then rapidly decreased to 0.2 {Omega}cm at 220 GPa. {copyright} {ital 1996 American Institute of Physics.}
