The ScCl3-Sc System

Description: Experimental data supporting lower valence halides of scandium were not found in the literature. Our investigation was of the phase diagram of the ScCl3-Sc system, and also the vapor pressure-composition isotherm (at 960 degree) for this system. Investigation of the ScCl3-Sc system presented particular difficulties in comparison with analogous systems for rare earth elements in that ScCl3 is highly volatile (boiling pt. = 967 degree); according to our data the vapor pressure is 512 mm Hg measur… more

The Heats of Reaction of Lanthanum Perchlorate Solutions with Perchloric Acid and with Hydrogen Halides

Description: The present paper is devoted to the determination of the heats of reaction of lanthanum ions with halogen ions within a broad concentration range of hydrogen halides. The enthalpies of the interaction of lanthanum perchlorate with perchloric and halogen acids increase with the increasing of acid molality from one to eight. The enthalpies of the interaction between lanthanum and halogen ions in water solutions are endothermic and decrease in the sequence; Cl > Br > J. The values support the fact… more
