Abstract

Measurements are reported of the electrical conductivity of solutions of Cs, Ca, Sr, Ba, and Yb in liquid ammonia. Cs-NH73 solutions were studied at concentrations above 6 mole% metal (MPM) and at temperatures from 200 to 300 K. Cesium and ammonia can apparently be mixed in any proportion near room temperature. In the case of the other metals, the concentration range is from 2 to 7 MPM at temperatures between 190 and 250 K. The observed conductivities ranged from 200 to 16 000 Ω−1 cm−1. The conductivity was observed to increase with temperature, except for Cs-NH3 solutions above 30 MPM. The present results are compared with those available on other metal-ammonia solutions, and with the behavior of simple liquid metals. In addition, the phase diagrams of the solutions are reported.
