Abstract
The program comprises basic research on ceramic materials with semiconducting and magnetic properties. Here investigation of grain boundaries and the study of microstructural models, which will explain and predict the most important specific electric and magnetic properties of the studied ceramic, will be performed. The programme will also consider the phase diagrams of oxide systems where phases with magnetic and semiconducting properties are to be expected. In addition, the programme is focused on the chemical properties and characterisation of nano-powders. Here the hydrothermal, sol-gel, microemulsional-based, sonochemical and other promising techniques are planned. The electronic ceramics planned to be investigated are based on donor-doped BaTiO3 and other systems with ferroelectric phases which might exhibit anomalies in electric resistance such as niobates and bismuthates, with a relatively high transition temperature. The investigation of magnetic ceramics will be concentrated on Mn, Zn, Ni and Cu based spinel ferrites. The aim of the programme is to study and elucidate the basic processes, which are essential for understanding of the formation and functioning of these materials. The final goal of the programme is to understand how the intrisinc properties and the grain boundary structure create the final extrinsic properties of a ceramic material. The programme proposed, i.e. the study of the grain boundary structure, in connection with transport phenomena, is related not only to the ceramics investigated but more broadly, to the majority of electoceramic materials. The semiconductivity and / or magnetic polarisation depend strongly on the status of the grain boundaries. So, the knowledge acquired during the study of the microstructural properties can also be important for the broad scientific community dealing with ceramic materials. Investigations of the oxide systems which include phases exhibiting magnetic and semiconducting properties and are open to design of technically important ceramic materials, are particularly valuable. The programme is important for Slovenia because of the domastic industry producing these ceramic materials. In the frame of the programme the education of students and postgraduates, as well as cooperation with foreign universities will take place. The results are to be published in highly ranked journals. Finally, these results will be used by experts from industry during the development and production of these materials.
