| Abstract [eng] |
The topic of the doctoral dissertation is „Synthesis and Characterisation of Magnesium Whitlockite Powders via a Low-Temperature Dissolution-Precipitation Process“. This thesis describes low-temperature Mg-WH dissolution-deposition syntheses using brushite and gypsum as starting materials. The chosen low-temperature dissolution-settling synthesis method is important to produce biocompatible calcium phosphate ceramics. The materials obtained by this method have physical and chemical properties similar to those of bone apatite. The aim of the research is to investigate the formation of Mg-WH from brushite and gypsum as starting materials via a low temperature dissolution-precipitation process, to explore Mg-WH phase formation and to control the synthesis conditions to influence the chemical composition, crystallinity and morphology of the resulting powder for potential applications in bone tissue regeneration. The experimental methodology section, which consists of four subsections, describes the reagents and solutions used, the synthesis of the samples, the equipment used for the characterisation of the samples and the analytical methodology. The first subsection lists the reagents used for the synthesis of the samples, indicating their purity, concentration and manufacturer. The second sub-section describes the synthesis of Mg-WH powder from brushite by the addition of different amounts of magnesium ion source to the reaction mixture. The third subsection describes the synthesis of Mg-WH samples from gypsum for phase transformation studies under static and rotating conditions. The fourth and final subsection is devoted to the characterisation of the synthesised products and the description of the equipment and measurement conditions used for the analysis. All the obtained results are discussed in a separate part of the dissertation and the conclusions are formulated. |
