Abstract
The area of glass formation in the systems TKCMC - Li2O - B2O3 and TKCMC - LiFe5O8 - B2O3 has been studied. The most interesting compositions have been determined and the density and temperature coefficient of linear expansion (TCLE) of glasses have been investigated. It was found that the glasses exhibit weak magnetic properties. The study of the magnetic properties of crystallized glass samples showed that crystallization greatly enhances the magnetic properties, reaching values of practical application due to the precipitation of lithium ferrospinel in the samples. Research on the specific volume electrical resistivity of crystallized lithium ferrite system samples showed that they exhibit pronounced positive temperature coefficient effects at different temperatures, which will allow their use in various types of sensors. The work done shows that the tailings of the Kajaran copper-molybdenum production can be successfully used to produce electronic materials.
