Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ПОЛИВАНАДАТ НАТРИЯ -- ПОЛИВАНАДАТ КАЛИЯ -- ПОРОШКИ АЛЮМИНИЕВЫЕ -- ОКИСЛЕНИЕ Аннотация: The effect of polyvanadates and vanadium oxide bronzes of alkali metals on aluminum-powder ozidation has been studied by thermogravimetry and x-ray phase analysis. The macromechanism of promotion of aluminum oxidation in which the catalytically active component is melted Na2AlxV12031 has been established. It is shown that the intermediate product of vanadiumcontaining slag9 processing can be used as an activator |
