Research in Physical-Chemical Processes by Method of Measuring Electric Conductivity in Ceramic Masses When Firing
The method of measuring the electric conductivity in clays and ceramic masses when firing consists of definition of the change in thespecific volume resistance of a ceramic samplewhen heating. Results of the study of the dependence of specific resistance on the temperature for samples made of low-melting clays, secondary raw materials and ceramic masseswith various component compositions are presented. The considered experimental materials reflect the output of adsorption and interlayer waters, the formation of a liquid phase,destruction of crystalline lattices of mineral, and formation of new ones. The methodology of measuring the dependence of specific volume resistance on the temperature makes it possible,in conjunction with other study methods, to more deeply study the physical-chemical processes in ceramic masses and establish optimal conditions of products firing.
