Literature Data

[1993Pav] synthesized binary Er-Li alloys by arc melting of the pure components (Li with 98.2 mass% and Er with 99.8 mass.% purity) in purified argon at atmospheric pressure. The specimens were subsequently annealed at 200°C for 240 h in tantalum containers and analyzed by X-ray diffraction. Complete immiscibility has been observed. [1998Gan] deduced the Er-Li phase diagram to be of peritectic type based on empirical formula. Samples have been prepared by melting the pure elements (Er and Li>99.7 mass% purity) in molybdenum crucibles in a resistance furnace and an argon overpressure of 0.5 MPa. The composition of the peritectic reaction was estimated from the experimentally determined transition temperature using another empirical relation. The experimental studies are summarized in Table 1...
