Contribution to the "Van-Arkel Method" for Purification of Metals; CONTRIBUCION AL METODO DE VAN ARKEL PARA LA PURIFICACION DE METALES
The process consists of the thermal decomposition of a volatile metallic compound by an incandescent filament on which the pure metal is deposited. The filament temperature is an essential point in the process development. From a theoretical point of view. curves were studied which determine the isothermic deposit of a metal. The process was divided in two parts; in the first, it was necessary to take into account variations in certain variables (emissivity, resistivity); in the second pant. the deposition takes place in a similar way to one followed by an incandescent filament while vaporizing at a constant temperature. Graphs are given with the course of variables. which have to be used in an industrial development. The experiment was worked out for the particular case of zirconium deposited on tungsten. (auth)
