Some electronic factors influencing superconductivity in some rare-earth-like elements and the beginning of the rare-earth series

AbstractAn innovative rare earth oxide-containing slag for hot metal dephosphorization was proposed, and the factors influencing the efficiency during the dephosphorization of hot metal using rare earth oxide-containing slags were also studied. An increase in the temperature up to 1,550°C is beneficial to the dephosphorization process, and the maximum degree of dephosphorization for slags containing 6 wt% rare earth oxides is 44.49%; further temperature increases would deteriorate the efficiency, and the degree of dephosphorization decreases to 37.38% at 1,600°C. An increase in the basicity of slags up to 3.0, and the rare earth oxide content up to 6 wt%, improves the dephosphorization efficiency; further increase in the basicity and rare earth oxide content, the efficiency has almost no change. It was also found that an increase in the quantity of slags is beneficial to the dephosphorization reaction.

The Rare Earth

Detailed examination of the strucures of the title salts, (tpy)LnCl3.xH2O, across the totality of the rare earth series shows a remarkable interplay of structural type and detail. The predominant phase is the previously studied monoclinic Cm array, a ≈ 7.5, b ≈ 16.6, c ≈ 9.8 Ǻ, β = 90.2°, V ≈ 2200 Ǻ3, Z = 2 formula units. For the initial members of the series (La → Nd ), x is 8; for Dy → Er and Lu, x = 7 is accommodated within the same lattice, as are intermediate degrees of hydration for Sm → Gd . A second monoclinic phase, P 21/c, a ≈ 11.6, b ≈ 13.9, c ≈ 13.8 Ǻ, β ≈ 92.3°, V ≈ 2200 Ǻ3, Z = 4 formula units, is found for Yb and Lu (x = 7); the same phase but with β acute (a ≈ 11.3, b ≈ 14.5, c ≈ 13.3 Ǻ, β ≈ 82.2°, V ≈ 2140 Ǻ3, Z = 4 formula units) is found for Tm (and Y) (x = 6). A less hydrated binuclear phase, x=1, has also been observed for Sm , a 10.179(3), b 9.928(4), c 9.748(4) Ǻα 112.61(3), β 109.85(3), γ 94.72(3)°, V 829.3 Ǻ3, Z = 1 dimer.
