| Popis: | The reactions of phosphorus in aluminium electrolyte and its fate in the electrolysis was studied using the thermodynamic analysis of possible chemical reactions between cryolite, alumina, and phosphorus compounds most probably present in the aluminium cells. POF3 was found to be the most probable gaseous phosphorus compound, which escapes from the electrolyte and is absorbed in the dry scrubbers. The formation of the reaction products of phosphorus was confirmed by the X-ray diffraction analysis and IR spectroscopy. ©1999 Canadian Institute of Mining and Metallurgy.

Pour ce faire, on a utilise l'analyse thermodynamique des reactions chimiques possibles entre la cryolite, l'alumine et les composes phosphoreux les plus probables dans les cellules d'aluminium. Le compose de phosphore gazeux le plus probable etait le POF3, lequel ... |
