Bioactive calcium phosphate coatings on zirconia ceramics
This doctoral thesis describes the synthesis and characterization of calcium phosphate (CaP) coatings on zirconia ceramics. The main application of coated zirconia is in medicine, particularly in the area of dental bone implants. Due to the favourable biological characteristics of CaP, it can be expected that the application of CaP …
Moderately porous zirconia ceramics for dental applications
This doctoral thesis describes the preparation of moderately porous Y-TZP ceramics with improved flexural strength. The main field of application is dentistry, where the elastic mismatch between the Y-TZP material and tooth substance influences the survival rate of fixed partial dentures (FPDs). By introducing porosity into the bulk samples a …
Innovative electroconductive ceramic composites based on Si3N4
This thesis describes an investigation of electrically conductive composites based on Si3N4 with dispersed TiN or ZrN particles fabricated by an in-situ composite method. The influence of the amount of conductive phase of the Si3N4/TiN and Si3N4/ZrN composites on the density, the flexural strength and the electrical conductivity were evaluated. …
The hydrolysis of AlN powder and its use for the synthesys of nanostructured alumina coatings
he thesis describes a study of aluminum nitride (AlN) powder hydrolysis in the temperature range between 5 °C and 90 °C. The analysis of the temperature dependence of the course of the hydrolysis and the reaction kinetics, along with a mechanistic model set up for the hydrolysis reactions, gives a …
