Abstract Ni, Cr, W, Mo, Al, Ti, B and misch metal were added separately or in combination into pure iron containing 0.166% of oxygen. Optical and chemical properties as well as crystal structure of various types of nonmetallic inclusions present in the alloys were studied. The inclusions identified as in these alloys are CeO_2, FeO (with Ni), FeO (with Mo), Cr_2O_3, Cr_3O_4, FeO·WO_3, α-Al_2O_3, α-Al_2O_3 (with Ni), α-Al_2O_3 (with Ti, Ni, Cr), TiN, α-Ti_2O_3 and a certain kind of boride. The present results confirmed that the composition and properties of a deoxidation product are mainly determined by the affinity between the alloying element used and oxygen.
