摘要
The electrical resistivity, rho, of liquid K-Sn and Cs-Sn alloys has been measured as a function of composition and temperature. The resistivities of both systems exhibit very sharp peaks close to the equiatomic composition. At the same composition, the temperature dependence of the resistivity has a deep minimum. The maximum resistivities are 3100 and 14200 muOMEGA cm respectively. Comparison with the Li-Sn and Na Sn alloys and with the alkali-lead systems strongly suggests that Zintl ions are formed in the liquid.
