(2013-08-27)
Thermal and spectroscopic studies on solid trivalent lanthanides and yttrium(III) α-hydroxyisobutyrates, Ln(C4H7O 3)3·nH2O were investigated employing simultaneous thermogravimetry and differential thermal analysis (TG-DTA), ...
Lithium-lanthanum double chromates
(1993-11-12)
Synthesis and crystallographic data are reported for low and high temperature forms of LiLa(CrO4)2. The compounds are closely related to lamellar rare earth phosphates and arsenates of sodium and to RbLu(CrO4)2. Lattice ...
Preparation of lanthanum doped Bi4Ti3O12 ceramics by the polymeric precursor method
(2006-08-01)
Lanthanum-modified bismuth titanate, Bi4 - xLaxTi3O12 (BLT) ceramics, with x ranging from 0 to 0.75 were prepared by the polymeric precursor method. Orthorhombicity of the system is decreased with the increase of lanthanum ...
Lanthanum cobaltite black pigments with perovskite structure
(2013-05-09)
In this work La1-xCaxCoO3 (x = 0-0.4) pigments were synthesized by the polymeric precursor method with heat treatments at 700, 800 and 900 C for 4 h. The powders were characterized by colorimetry, UV-vis spectroscopy and ...
Synthesis, characterization and spectroscopy of the europium doped lanthanum trimetaphosphate
(1998-07-24)
Orthorhombic modification of europium doped lanthanum trimetaphosphate has been prepared. The compound was obtained by precipitation of rare earth chloride solution with trimetaphosphoric acid. The characterizations were ...
Strain behavior of lanthanum modified BiFeO3 thin films prepared via soft chemical method
(American Institute of Physics (AIP), 2008-11-15)
Pure and lanthanum modified BFO (LaxBi1-xFeO3, x=0.0, 0.08, 0.15, 0.30) thin films were fabricated on Pt(111)/Ti/SiO2/Si substrates by the soft chemical method. The effect of La substitution on the structural and electrical ...
Thermal behaviour of the basic carbonates of lanthanum-europium
(Elsevier B.V., 1995-04-15)
The basic carbonates of lanthanum with 10%, 20%, 50% and 80% of europium were prepared by precipitation from homogeneous solutions via the hydrolysis of urea, without the addition of an auxiliary anion, at two different ...
Solid-state compounds of 4-chlorobenzylidenepyruvate with lanthanides preparation and thermal studies
(2000-01-01)
Solid-state compounds Ln-4Cl-BP, where Ln represents lighter trivalent lanthanides and 4Cl-BP is 4-chlorobenzylidenepyruvate, were prepared. Thermogravimetry, derivative thermogravimetry (TG and DTG), differential scanning ...
