Sintering of Advanced Cubic Ceramic Materials
Hrubý, Jan ; Pouchlý, Václav (referee) ; Maca, Karel (advisor)
This bachelor's thesis deals with the literature search on preparation of advanced ceramic materials. It compares the sintering and properties of cubic ceramics with ceramic materials with different crystal structures. The experimental section is devoted to preparing tetragonal ZrO2 ceramic (doped with 3 mol% Y2O3) and cubic ZrO2 ceramic (doped with 8 mol% Y2O3). These ceramics were prepared using two-step sintering combining pressure-less sintering with hot isostatic pressing (HIP). The goal was to prepare dense ceramics with homogenous microstructure. Another studied material was Y2O3 with micrometer sized particles. Microstructure and optical properties of studied materials were evaluated.

Study of microstructure evolution during final stage of sintering of advanced ceramic materials
Hrubý, Jan ; Salamon, David (referee) ; Maca, Karel (advisor)
This diploma thesis deals with the study of microstructure development during the final stage of sintering of two zirconia based ceramic materials (tetragonal ZrO2 doped with 3 mol% of Y2O3 and cubic ZrO2 doped with 8 mol% of Y2O3). Conventional, microwave and SPS sintering methods were used. Achieved relative densities and mean grain sizes were evaluated for sintered materials. It was found that the non-conventional sintering methods are capable of rapid processing of ceramics with improved microstructure compared to conventional sintering.
