Abstract

Kaolin samples of the Malinovetskoe deposit are used to study the processes of loosening and bloating of clay rocks in roasting at a temperature exceeding the sintering one. It is shown that the bloating is a result of oxidation-reduction reactions between the admixtures contained in the clays when they are heated under the conditions of diminished viscosity of the glass phase. In addition to the possible influence of these factors the loosening is connected with crystallization of new phases.
