The main research objectives

Inorganic chemistry, solid state chemistry. Crystal chemistry of transition metal oxides, hydroxides, and their solid solutions in the light of double substitution caused by the hydroxylation of anionic sublattice. Phase transitions and real structure of goethite and aluminogoethite. Cation distribution in the lithium-manganese-iron oxides. Effect of cation and vacancy distribution on the magnetic and electrical properties of mixed spinel oxides. Structural evolution of defects in nonstoichiometric ferrimagnetic phases formed by hydrothermal, sol-gel and thermal methods. Structural and magnetic studies on defect spinel ferrites and lithium-manganese oxides. Powder X-ray diffraction coupled with Rietveld refinement methods.
