In the first period of existence of the Chair of Mineralogy and Petrography the main subject of research was the petrographic analysis of rocks and minerals collected in Lublin Upland, Swietokrzyskie Mountains and the Tatra Mountain. Next, in the Chair of Mineralogy and Crystallography, the crystalochemistry of the compounds and the epitaxial crystal growth were investigated. Later, the main study areas in the Crystallography Laboratory were the methods of synthesis of the sparingly soluble metal salts, the phase analysis of different form of the cation zeolites, investigation of polidyspersional matertials using small angle X-ray scattering and X-ray diffraction.
At the moment, the research carried out in the Department of Crystallography utilizes X-ray, as the main method of investigation: the diffraction of single crystal species, as well as the powdered and amorphic phases. The main aim of the X-ray crystal structure analysis is the study of stereochemistry of organic compounds which include natural products (derivatives of alkaloids, saccharides, amino acids, steroids) and drug molecules and compounds of biological importance. Determination of the molecular structure and analysis of the intermolecular interactions extends our knowledge about the mechanism of drug activity. The research in our department also includes polymorphism, solvatation, and isostructural molecular crystals formation, these problems are of a great importance to the pharmaceutical industry. In 1998, KBN research grant and an equipment investment grant supported the acquisition of a single crystal X-ray diffractometer KM4.
Applied crystallography, mainly small angle X-ray scattering (SAXS) method, is used for studies of the porous phase structures (for example zeolites, silica gels, glass, carbons, aluminium oxides and zirconium oxides) and starch.
