    Torres Rodríguez, Jorge Alberto; Kalmár, József; Menelaou, Melita; Čelko, Ladislav; Dvořák, Karel; Cihlář, Jaroslav; Cihlář, Jaroslav; Kaiser, Jozef; Győri, Enikő; Veres, Péter; Fábián, István; Lázár, István (Elsevier, 2019-07-01)
    Monolithic, structurally stable zirconia (ZrO2) aerogels can be used in high temperature applications and as medical implants. The macroscopic properties of these solids can be fine-tuned by the appropriate thermal treatment ...
  • Machinability and properties of zirconia ceramics prepared by gelcasting method 

    Kaštyl, Jaroslav; Chlup, Zdeněk; Šťastný, Přemysl; Trunec, Martin (TAYLOR & FRANCIS LTD, 2020-08-17)
    The machinability of newly developed zirconia ceramics for computer numerically controlled milling (CNC) was investigated. The zirconia blanks were prepared by the gelcasting method and tested in the green and two pre-sintered ...
