Perfection of the method of definition of degree of restoration of chromium ? containing oxide raw materials

Phase transformations of the process of carbon-thermal of chromium oxide Cr2O3 were investigated. The high probability of parallel carbide-forming along with metallization was revealed. Fractographs and results of the x-ray microanalysis confirmed and specified the picture of phase transformations. On the basis of a complex of research an express method of definition of degree of restoration chromium ?containing raw materials, providing productivity increase by 10-12 times, in comparison with known analytical ways and meeting express analysis requirements was s developed and tested
