Abstract
The electrical conductivity of AgI has been determined to 100 kbar at room temperature, using a 1‐kc/sec 20‐V pulse as source. Conductivity increases with pressure in the low‐pressure phase, stable to 2.5 kbar, and then decreases in the two high‐pressure phases. The increase in the low‐pressure phase is in agreement with its negative thermal expansion. A reversal of slope above 45 kbar in the cubic (NaCl‐type) phase is explained in terms of the formation of I3−, recently reported from spectroscopic studies, in amounts decreasing with pressure to 70 ± 5 kbar, where I3− is no longer present.Keywords
