Department of Mechanochemistry
Head of the department:
Research in Department of Mechanochemistry focuses on the elaboration of mechano-chemical, physico-chemical and chemical methods of synthesis and application of nanocrystalline materials and their composites prepared from precursors based on natural minerals, synthetic substances, as well as selected components of intermediate products and wastes from various industries.
RESEARCH FOCUS
Mechanochemistry is a branch of chemistry, which is concerned with the chemical and the physic-chemical changes of substances of all states of aggregation due to the influence of mechanical energy. According to this definition two main processes are applied in the department:
- mechanochemical solid state synthesis, where the new materials are produced and
- mechanical activation of solids, where the improvement of their properties is obtained.
Potential for application of the products rests in their implementation to the:
- electrotechnical industry – semiconductors, photovoltaic cells, batteries and fuel cells based on sulfides, oxides and silicates,
- hydrometallurgy – recovery of precious (gold, bismuth), economically important (copper) or on the other hand undesirable metals (antimony, arsenic),
- ecology – cleaning of waters, CO2 storage,
- medicine – drugs based on minerals.
