FIELD: chemistry.
SUBSTANCE: invention relates to production of structural materials and can be used in the technology of ceramic wall articles, particularly ceramic brick and stone. The crude mixture for making ceramic wall articles has components in form of a mud-like portion of iron ore beneficiation wastes - 75-85; natural clay material 10-15; and vanadium slag 5-15.
EFFECT: replacing expensive, chemically pure vanadium oxide (V2O5) in the crude mixture with a metallurgy by-product - vanadium slag, and reducing the amount of clay material in the mixture, while lowering the hazard class of the vanadium-containing component.
