In the main part, author treats the equilibrium of Fe-C-O2-system at steel making temperatures by melting carbon and oxygen bearing iron in the gas stream of carbon mono-oxide and dioxide mixture. As the results of his experiment, it was proved that the oxygen content of the molten steel in equilibrium with the gas phase, is proportional to the ratio pco2/pco, and carbon content to p2co/pco2. On these accounts, he proposed that the two equilibriums, FeO(Fe)+CO=Fe+CO2 and C(Fe)+CO2=2CO, should be considered simultaneously as the carbon-oxygen equilibrium in steel making process instead of FeO(Fe)+C(Fe)=Fe+CO as was usually accepted. Further he constructed also the equilibrium diagram of Fe-C-O2-system qualitatively in the region of molten steel.As an appendix of his main paper, he described the hydrogen reduction method of oxygen determination in iron and steel. Some remarkable points of his method of determination are in the treatment of reduction products, H2O, CO2 and CO. Here H2O was absorbed by P2O5 and CO2 by soda lime as usually, CO is oxidized by I2O5 to CO2 selectively and after retaining free iodine with metallic copper chips, secondary formed CO2 absorbed by soda lime and weighed.

Equilibrium of phosphorus-carbon-oxygen in liquid iron in contact with a mixture of solid calcium phosphate and calcium oxide was studied in a controlled gas atomosphere of CO-CO2 gas mixture in the range of 0.03-1.2% of phosphorus in liquid iron at 1530.., 1560.., and 1585... It was found that the stable phase of calcium phosphate was of tetracalcium phosphate, 4CaO.P205, at the presence of free lime in this experiments.The results obtained were summerized as follows: (1)(1b)(1c)(2)(2b)(2c)(3)(3b)(3c)
