    Material analysis of meteorites
    (Technická Univerzita v Liberci, 2007-01-01) Leonczak, Emil; Mitura, Stanislav
    The aim of master`s thesis was to carry out the material analysis of meteorites. Thanks to their extraterrestrial origin meteorites are very interesting objects of scientific research. Carbon contained in meteorites can be found in various forms, i.e. graphite, diamond, lonsdaleite-extraterrestrial hexagonal diamond. This carbon and other phases and compounds can be source of information about the solar system formation, the conditions under which the minerals crystallized and transformed to the present state. Meteorites in this work were analysed paying special attention to the presence of carbon and allotropic forms in which carbon can be found. Theoretical part of thesis presents the division of meteorites, allotropic forms of carbon and methods of carbon detection in this extraterrestrial objects. Experimental part contains results of own research carried out with using optical microscopy, Scanning Electron Microscopy with X-Ray microanalysis, Raman spectroscopy and nanohardness measurement method. Results are presented in tables, graphs and pictures.
