VITTORF, Nikolay was born on April 25, 1869.
1904, in the course of thermal analysis of the nitrogen oxide-nitrogen dioxide system, demonstrated that November and N2 04 form only one compound - nitrogen anhydride N203. 1909, on the basis of the theory of thermodynamic potential, provided conclusions to all types of diagrams for binary systems Hypothesized the existence of carbides with the probable composition Fe4C, FeC and FeC2.
Despite for eign criticism of this hypothesis, it was never refuted experimentally.
