Study of the Thermal Characteristics of Phosphate Raw Materials in the Annealing Temperature Range

Abstract—In this paper, the thermal characteristics of phosphate raw materials have been studied, including thermal conductivity and volumetric heat capacity in the temperature range that has practical significance in the chemical and technological system of thermal preparation of raw materials. The method of the regular regime of the third kind and the method for solving the inverse heat-conduction problem have been used based on the joint solution of the equations of heat transfer and the kinetics of chemical reactions taking into account the most important accompanying phenomena. A dilatometric analysis of the studied samples of phosphate raw material has been presented.
