Some measurements of the electrical resistivities of dilute liquid amalgams containing alkali and alkaline-earth elements

The electrical resistivities ( rho ) and temperature coefficients of resistivity ( delta rho / delta T) have been measured for binary amalgams containing up to 1 at.% of Li, Mg, Ca, Sr and Ba. Amalgams with Ca, Sr and Ba exhibit small but real increases in both rho and delta rho / delta T on initially alloying; both these properties go through maxima at approximately 0.2 at.% solute. Amalgams with Li or Mg give similar results for delta rho / delta T but rho decreases very slowly on alloying. These results are in marked contrast to those for amalgams with solutes from the B sub-groups of the periodic table.
