Freeze casting of hierarchically structured highly porous γ-Al2O3 monoliths
Highly porous ceramic γ‒Al2O3 monoliths are important in many applications, e.g., catalysis, thermal insulation and adsorption, yet they still have a lot of unrecognized potential. There is a lot of incentive to employ simple and green fabrication processes for the preparation of such porous ceramic materials; however, many challenges, especially …
A New Synthesis Route to Pb(Mg1/3Nb2/3)O3-Based Materials by the Controlled Agglomeration of Reagent Particles
In this thesis we demonstrate a new, simple, and ecient method for the solid-state synthesis of oxides with a complex chemical composition. We modify the traditional solidstate synthesis method, which is used in the majority of ceramics laboratories around the world, in order to prepare multi-metallic oxide powders from classic …
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 …
