Investigation of the thermophysical characteristics of minerals at various heating parameters

Abstract

The study of natural minerals in the production of heat and electrical insulating materials is of particular practical interest for the study of their thermophysical characteristics. The regularities of changes in the heat capacity of minerals when heated in production and operating conditions are of particular interest. Natural minerals of wollastonite and quartz were considered as the object of research. The heat capacity of these minerals was measured in an apparatus with a three-dimensional sensor and a panel for automatic control of gas flows, when heated to the temperature of 1600ºС by the calorimetric method. Based on the experimental results, graphs of the dependence of the heat capacity of mineral samples on temperature were constructed.
