The paper considers the problem of using technogenic products in the production of construction materials thus obtaining ceramic products with specified properties both in Russia and abroad. It provides data on chemical and mineralogical composition of initial raw materials, defines pre-calcination and calcination properties of clay and nickel slag. Compositions with different percentage of clay/slag are developed and two-factor experiment is carried out, where the first factor is the percentage of slag in a sample, while the second factor is the sintering temperature of samples. The diagrams show the influence of material composition of clay/slag charge mixture on compression strength, water absorption and density of test samples after firing at a temperature of 900, 950, 1000 and 1050 °C. The obtained results allowed identifying the need for sintering of masses from clay of Khalilovsky deposit with nickel slags of OAO Yuzhuralnickel of Orenburg Region in the production of ceramic brick.
