This paper presents the comprehensive study findings of the high-ferriferous wocheinite (a bauxite variety) of Timan deposit to evaluate the possibility of its application in the aluminosilicate ceramics production. The study was carried out by chemical, X-ray phase and thermal analysis on two samples before and after calcination. According to the obtained data, investigated material is of practical interest as a hardening and mineralizing additive to produce high-strength aluminosilicate ceramics. The strength improving ceramic structures, based on clay and bauxite raw materials mixture, is possible due to the binding of silica, which is released from the structure of kaolinite by aluminum oxide as a product of boehmite and hydrargillite dehydration to the secondary mullite.
