This paper is focused on the development and modification of inorganic refractory nanofibers for advanced applications, made from the most available ceramic raw materials (Al2O3 and SiO2) in the right proportion for crystallization of mullite, commonly used high-temperature material. The intention is to create a modifiable refractory material for use in electrotechnical applications as electrodes, separators, or a solid electrolyte in a new type of safe solid-state batteries. For these reasons, the nanofibers are modified with different conductive materials, for example different types of spinels. Spinels with the formula AB2O4, specifically CuCr2O4, have been studied due to their significant electrical and magnetic properties, that are suitable for their intended purposes.
