In smelting the titaniferous iron ore in modern blast furnace, the non-metallic compounds of titanium being formed easily has been discussed in my previous papers with the results of various experiments. The reactions are based chiefly on the formation of the infusible compounds of titanium, owing to the effects of nitrogen in blast in high tempereture working. Titanium as reduced exists in slag and pig iron ingeneral in the forms of carbide (TiC) nitride (TiN) and cyanonitride (Ti_5CN_4?) In this paper the author quotes the leading conclusions, which have previously been proposed about the compounds of titanium and gives a brief discussion. To investigate the formation mechanisum of non-metallic compounds of titanium from titanic oxide in the furnace atomosphere the author has endeavoured to make the more pure one of several kinds of the compounds of titanium, and studied the effect of iron for those samples. They have been melted in a high vucuam electric furnace with iron, the products being examined both microscopically and analytically. The author discusses also graphycally the mode of change of titanic oxide into the non-metallic compounds of titanium the blast furnace, and gives his idia to smelt the titaniferous iron ore.
