Melting enthalpies and high-temperature heat capacities of lower silicides of YTTRIUM-subgroup rare-earth metals

  • Published:
Powder Metallurgy and Metal Ceramics Aims and scope

Components of the high-temperature heat capacity of REM silicides, Ln5Si3, and variation in their melting enthalpies in the Gd5Si3 → Ln5Si3 series are analyzed. A method for calculating the high-temperature thermodynamic properties of the compounds still to be experimentally studied is proposed. The experimental temperature dependences for the enthalpies of Ln5Si3 (Ln = Gd, Er, Lu) are used to calculate the melting enthalpies and temperature dependences of the heat capacity for other yttrium-subgroup silicides.
