There were discussions on the adsorption mechanisms of carbon monoxide by manganese in the vacuum fusion furnace. Thanheiser reported that manganese films deposited on the walls of the vacuum fusion furnace adsorbed carbon monoxide, while Wood <I>et al</I>. and Sawa reported that carbon monoxide adsorption by manganese occured when it was depositing. Carbon monoxide was allowed to circulate in a furnace and gas adsorption curves by manganese and chromium were measured at the different furnace conditions. By means of this method whether the adsorption of carbon monoxide occured at the depositing metal vapor or on the deposited films were partly clarified. Much more carbon monoxide was adsorbed by chromium vapor than chromium films on the furnace walls, although in the case of manganese it was adsorbed rather by films than vapor. The adsorption speed by manganese vapor was about 300 times greater than that by chromium vapor.<BR>In the analysis of steel samples containing manganese the adsorption mechanism by manganese might be affected by other components.<BR>These results will give useful informations for designing the apparatus.
