  • Densification of Magnesium Aluminate Spinel Using Manganese and Cobalt Fluoride as Sintering Aids 

    Talimian, Ali; Pouchlý, Václav; Maca, Karel; Galusek, Dušan (MDPI, 2020-01-01)
    Highly dense magnesium aluminate spinel bodies are usually fabricated using pressure-assisted methods, such as spark plasma sintering (SPS), in the presence of lithium fluoride as a sintering aid. The present work investigates ...
  • 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), ...
  • 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 ...
  • Transparent magnesium aluminate spinel: Effect of critical temperature in two-stage spark plasma sintering 

    Talimian, Ali; Pouchlý, Václav; El-Maghraby, H.F.; Maca, Karel; Galusek, Dušan (ELSEVIER SCI LTD, 2020-06-01)
    The discolouration of magnesium aluminate spinet caused by carbon contamination is a main drawback of fabricating transparent bodies by spark plasma sintering (SPS). In this study, a two-stage heating rate profile was used ...
