  • 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 ...

  • 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), ...

  • Master Sintering Surface – A Practical Approach to Its Construction and Utilization for Spark Plasma Sintering Prediction 

    Pouchlý, Václav; Maca, Karel; Xiong, Yan; Shen, Zhijian (International Institute for the Science of Sintering, 2012-08-01)
    The sintering is a complex thermally activated process, thus any prediction of sintering behaviour is very welcome not only for industrial purposes. Presented paper shows the possibility of densification prediction based ...

  • Microstructural and Electrical Properties of Cordierite-based Ceramics Obtained After Two-step Sintering Technique 

    Obradović, Nina; Filipović, Suzana; Dordević, Nataša; Kosanović, Darko; Pavlović, Vladimir B.; Olćan, Dragan; Dordević, Antonije; Kachlík, Martin; Maca, Karel (International Institute for the Science of Sintering, Beograd, 2016-05-01)
    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, ...

  • Microstructure and Phase Composition Of Steatite Ceramics Sintered by Traditional and Spark Plasma Sintering 

    Terzić, Anja; Obradović, Nina; Pouchlý, Václav; Stojanović, Jovica; Maca, Karel; Pavlović, Vladimir B. (International Institute for the Science of Sintering, Beograd, 2018-03-01)
    The influence of the sintering method on the mineral phase transformations and development of the crystalline microstructure of steatite ceramics was investigated. The steatite samples were fabricated from talc and bentonite ...

  • Optical, mechanical and fractographic response of transparent alumina ceramics on erbium doping 

    Drdlík, Daniel; Drdlíková, Katarina; Hadraba, Hynek; Maca, Karel (Elsevier, 2017-11-01)
    Alumina ceramics found their utilisation in many applications which can be further extend by attaining functional properties; in our case the transparency obtained through precise processing and photoluminescence due to ...

  • A Practical Approach for the Calculation of the Activation Energy of the Sintering 

    Pouchlý, Václav; Hrubý, Jan; Maca, Karel (International Institute for the Science of Sintering, 2016-12-15)
    Newly developed software for calculation of activation energy (Qs in the following) of sintering using the Wang and Raj model is presented. To demonstrate the practical potential of the software and to evaluate the behaviour ...
