    Cordierite-based ceramic materials are attracting much interest for their various applications in industry, for manufacturing multilayer circuit boards, catalytic converters, filters, thermal insulation, kiln furniture, ...
  • Advantages of Combined Sintering Compared to Conventional Sintering of Mechanically Activated Magnesium Titanate 

    Filipović, Suzana; Obradović, Nina; Pavlović, Vladimir B.; Kosanović, Darko; Mitrić, Miodrag; Mitrović, Nebojsa; Pouchlý, Václav; Kachlík, Martin; Maca, Karel (International Institute for the Science of Sintering, Beograd, 2014-09-01)
    In this article, the advantages of combined sintering in comparison with the conventional one, of mechanically activated magnesium titanate ceramic were investigated. The stoichiometric mixtures of MgO and TiO2 were ...
  • Availability of Suitable Raw Materials Determining the Prospect for Energy Storage Systems Based on Redox Flow Batteries 

    Vanýsek, Petr; Novák, Vítězslav (Faculty of Mining, Ecology, Process Control and Geotechnologies (FBERG), Technical University of Kosice, 2018-04-30)
    Successful large-scale deployment and manufacturing of newly designed products depends on the availability of raw materials and therefore even fundamental research on electrochemical energy sources cannot ignore the need ...
  • Luminescent Er3+doped transparent alumina ceramics 

    Drdlíková, Katarina; Klement, Róbert; Drdlík, Daniel; Spusta, Tomáš; Galusek, Dušan; Maca, Karel (Elsevier, 2017-07-01)
    We report on successful preparation of Er3+doped transparent alumina (0.1–0.17 at.%) exhibiting visible light photoluminescence using wet shaping method and hot isostatic pressing. The effects of dopantamount, type of ...
  • Luminescent Eu3+-doped transparent alumina ceramics with high hardness 

    Drdlíková, Katarina; Klement, Róbert; Hadraba, Hynek; Drdlík, Daniel; Galusek, Dušan; Maca, Karel (Elsevier, 2017-05-17)
    The Eu3+-doped transparent aluminas were prepared by wet shaping technique followed by pressureless sintering and hot isostatic pressing. The effect of dopant amount on microstructure, real in-line transmission (RIT), ...
  • Optical, mechanical and fractographic response of transparent alumina ceramics on erbium doping
