Seebeck coefficient and electrical resistivity of some rare earth ternary sulfides La/sub 3-x/M/sub x/S/sub 4/ (M = Sm, Eu, Yb)

Conference Nakahara, J F; Tschetter, M J; Beaudry, B J; ...

Binary lanthanum sulfides with compositions between La/sub 2/S/sub 3/ and La/sub 3/S/sub 4/ form a continuous series of solid solutions in the high temperature gamma form and have been reported to have high figures of merit. In this study, in order to achieve increased stability of the gamma form, compounds with the formula La/sub 3-x/M/sub x/S/sub 4/ (M = Sm, Eu, Tb and x = 0.1 to 0.9) were prepared. The Seebeck coefficients and electrical resistivities of these ternary sulfides are reported as well as some preliminary results on their long term thermal stability. The compounds La/sub 3-x/M/sub x/S/sub 4/more »« less
Syntheses, crystal structures, and comparisons of rare-earth oxyapatites Ca2RE8(SiO4)6O2 (RE = La, Nd, Sm, Eu, Yb) and NaLa9(SiO4)6O2

Journal Article Crum, Jarrod [BATTELLE (PACIFIC NW LAB)]; Chong, Saehwa [BATTELLE (PACIFIC NW LAB)]; Peterson, Jacob A. [BATTELLE (PACIFIC NW LAB)]; ... - Acta Crystallographica. Section E: Structure Reports Online

Six different rare-earth oxyapatites including Ca2RE8(SiO4)6O2 (RE = La, Nd, Sm, Eu, Yb) and NaLa9(SiO4)6O2 were synthesized using solution-based processes followed by heat treatments. The crystal structures of the synthesized oxyapatites were solved from X-ray powder diffraction (XRD) and electron probe microanalysis (EPMA). All the oxyapatites were isostructural with the hexagonal space group P63/m and showed similar unit cell parameters. The isolated [SiO4]4- tetrahedra in each crystal are linked by the cations at 4f and 6h sites occupied by RE3+ and Ca2+ in Ca2RE8(SiO4)6O2 or La3+ and Na+ in NaLa9(SiO4)6O2. The lattice parameters, cell volumes, and densities of the synthesizedmore »« less
