Abstract

A ceramic material was obtained based on a mixture of Krasnoyarsk clay and dearsenization cake from the sludge dumps of the Tuvacobalt Mining and Processing Plant. As a result of firing at 850°C, a new phase—nepheline—formed in the ceramic sample containing clay and cake. The composition of the ceramic sample also includes quartz and plagioclase (albite) phases. The ceramic sample based on Krasnoyarsk clay and dearsenization cake, fired at 850°C, exhibits sufficiently high strength, reaching 37.4 MPa.
