Lanthanum Activity in La–U–Ga–X Systems (X = Al or In)

Lanthanum activity was determined for the first time in La–U–Ga–X (X = Al or In) alloys. Ga–In and Ga–Al alloys were taken in the eutectic composition (21.8 wt.% In and 1.6 wt.% Al, respectively). Measurements were performed between 573 and 1073 K employing the e.m.f. method. Keywords: Lanthanum; Uranium; Gallium-Indium Eutectic; Gallium-Aluminium Eutectic; Activity; Thermodynamics

THERMODYNAMIC PROPERTIES OF RARE EARTH ELEMENTS IN La–RE–Ga–In (RE = Nd, Y) ALLOYS

Thermodynamic properties of La, Nd, and Y were studied in pseudo-ternary systems La–Nd–(Ga–In)eutand La–Y–(Ga–In)eut. Temperature dependences of lanthanum, neodymium, and yttrium activity in the studied alloys were determined at 300–800 oС employing the EMF method

LANTHANUM AND URANIUM SOLUBILITY IN Ga-In AND Ga-Al EUTECTIC BASED ALLOYS

Solubility of lanthanum and uranium was determined in gallium-aluminum and gallium- indium eutectic alloys between 573-1073 K using sedimentation method

CORROSION BEHAVIOR OF YEP-823 TYPE STEEL IN URANIUM CONTAINING CHLORIDE MELTS

Corrosion of YeP-823 type steel in the melts based on LiCl and 3LiCl–2KCl containing uranium chloride was studied at 500 and 650 oC. Corrosion rates and mechanism, structural changes in the material studied were determined
