Abstract
The phase diagram of the ternary system Li-In-Sb is determined at 400 °C by electrochemical techniques. The lithium content of samples with different In : Sb ratios is varied by coulometric titration. The equilibrium lithium activities are obtained from emf measurements. Two new ternary compounds, Li3InSb2 and Li6InSb3 with a wide range of stoichiometry, exist along the quasibinary cut InSb-Li3Sb. Both compounds are in equilibrium with In and Sb. Li3Sb co-exists with all Li-In phases. Semiconducting phases of narrow ranges of stoichiometry show generally fast chemical diffusion rates. The In rich phases have large stoichiometric widths and equilibrate much more slowly.Keywords
