Abstract:

Results are provided for a thorough study of a valuable variety of engineering stone, i.e. contemporary vanadium slags, that are a class of ``artificial (secondary) technogenic ore{''} for preparing a whole range of vanadium compounds and alloys. Chemical, petrographic, x-ray phase analysis and x-ray microanalysis are used to determine the mineral (phase) composition, to study phase-by-phase distribution of elements, and to specify slag microstructure. A temperature-time sequence is established for crystallization of spinellid and various silicates during molten slag cooling. The information obtained is necessary for obtaining the required properties of slag, and it is also interesting for the petrology of ore ultramafites. In view of the features of the mineral composition and microstructure contemporary vanadium slags are related to refractory materials (refractoriness similar to 1600 degrees C).
