Effective use of fluoride in silicate systems determined a significant change in the structure of the crystallization heat treatment of ceramic materials. Found that the addition of fluoride to the kaolin mineralizing with dynamic viscosity in the range of firing h = (0,6-6) Pa × s results in the acceleration phase formation in the products of burning. A characteristic feature is the fact that the addition of NaF and CaF2 interact with kaolinite and its degradation products to a temperature maximum exotherm to form solid solutions with the oxides of aluminum and silicon at 900 °C and the eutectic melt with each other or with the components of the charge. In relation to hydromica montmorillonite clay found a significant reduction in the dissociation temperature of CaCO3 in the presence of NaF and mineralizer shift decarbonization zone to lower temperatures.
