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 Vapor Pressures of VCl2, VCl3, VBr2, and VBr3 by Knudsen Effusion

Description: Technical report. From Abstract : "The vapor pressures of crystalline VCl2, VBr2, VCl3 and VBr3 have been measured by the Knudsen effusion method using pyrex and Vycor effusion cells. ... During the measurements on VCl3 and VBr3 dissociation and disproportionation of the samples occurred simultaneously with the simple vaporization. However, because the product of each of these processes was collected separately during an experiment, the vapor pressure due to sublimation was obtained without dif… more
