  • 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), ...
  • Processing and properties of luminescent Cr3+ doped transparent alumina ceramics 

    Drdlíková, Katarina; Klement, Róbert; Drdlík, Daniel; Galusek, Dušan; Maca, Karel (Elsevier, 2020-07-01)
    Transparent Cr2O3-doped alumina ceramics were prepared by slip casting, followed by pre-sintering in ambient atmosphere and hot isostatic pressing. The effect of dopant concentration on material properties, including ...
  • Thermal annealing effects in polycrystalline EuTiO3 and Eu2Ti2O7 

    Schell, Juliana; Kamba, Stanislav; Kachlík, Martin; Maca, Karel; Drahokoupil, Jan; Rano, B. Rahman; Gonçalves, Joo Nuno Santos; Dang, Thien Thanh; Costa, Angelo; Noll, Cornelia; Vianden, Reiner; Lupascu, Doru C. (AIP Publishing, 2019-12-01)
    Using time-differential perturbed angular correlation of gamma rays, we investigated the electric-field gradient of polycrystalline EuTiO3 and Eu2Ti2O7, with Hf-181(Ta-181) as a probe, following different thermal treatments. ...
  • Transparent alumina ceramics: Effect of standard and plasma generated stabilizing approaches in colloidal processing 

    Drdlíková, Katarina; Maca, Karel; Sláma, Martin; Drdlík, Daniel (Wiley, 2019-10-04)
    The study is focused on an optimization of the slipcasting process used for the fabrication of the transparent/translucent alumina ceramics; more precisely, on specifying the most appropriate way to stabilize the cast ...
  • 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 ...
  • Properties of BaTiO3/Al2O3 Laminate Structure by Nanoindentation 

    Chlup, Zdeněk; Drdlík, Daniel; Fides, Martin; Kovalčíková, Alexandra; Hadraba, Hynek (Elsevier, 2020-02-19)
    The proposed material design of BaTiO3/Al2O3/ZrO2 laminate structure predetermined for energy harvesters taking advantage of residual stresses developed during processing was prepared by electrophoretic deposition. The ...
