The Eu-Se System

Additional data for EuSe and data for phases in the EuSe-M2Se3 systems are found in Section 29.1.2.1 and 29.1.2.5, on pp. 7 and 58, respectively. 

The specimens were prepared in evacuated L-shaped quartz capsules with separate localization of the components. The components at 50 at.% Se were contained in corundumized

The great stability of Eu probably precludes the formation of EuSe2, Benacerraf et al. [2]. Compounds Eu3Se7 and EuSe3 are, however, reported as intermediate phases in the Eu-Se system, see p. 180.
