We consider the phase behavior of a symmetric AB diblock, blended with corresponding A and B homopolymers, all of equal chain length. Evaluating the phase diagram in mean-field theory at all compositions of the ternary blend, we find no hexagonal and cubic phases. However, up to three distinct lamellar phases can coexist, one being symmetric and the other two being asymmetric. For strong incomp...

The phase diagram of the ternary system L i I n S b 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-...
