Abstract
The electrical conductivity of cuprous chloride containing a dispersion of fine alumina particles was studied as a function of volume fraction (0–0.212) and particle size (0.3 and 0.06 μm initial particle size). At low temperatures the ionic conductivity may be increased by as much as two orders of magnitude. The enhanced conductivity, Δσ, was proportional to the surface area of the added alumina. Both these data and the earlier data of Liang (1) were fitted to a relation, where is the radius of the alumina dispersoids and the volume fraction.
