Title Generation of cadmium fume from alloy surfaces
Bibliographic information 2nd quarter 1985, Vol.29, No.2, p.181-189. Illus. 11 ref.
Abstract The theoretically calculated proportion of cadmium in metal fumes released into both air and an inert atmosphere from 9 different alloys heated to 700°, 800° and 900°C was compared with the observed proportion in experiments. The experimental values agreed closely with the predicted ones, suggesting that flux had little effect on metal fume composition and that a direct metal evaporation process was involved. There was also evidence of 2 other evaporation mechanisms: evaporation into bubbles created by the loss of volatile flux components and evaporation into bubbles created by the hydrogen generated by the reaction of acidic flux and alloy metals. The understanding of these mechanisms can contribute to effective fume emission control methods.
