Diplomová sa zaoberá štúdiom spojivového systému solu oxidu kremičitého a jeho charakterizáciou predovšetkým pomocou metód termickej analýzy. V diplomovej práci je tiež využitá metóda reologie na stanovenie času gelatinácie, metóda TG/DTA na stanovenie exo a endotermických efektov pri zahrievaní, metóda FT-IR na rýchle stanovenie zloženia vzoriek, XRD na stanovenie fázového zloženia vzoriek a metóda SEM na pozorovanie topografie vzoriek. Ako gelatinačné činidlo je použitý MgO, ako plnivo reaktívna alumina.
The master thesis deals with the study of the binder system of silica sol and its characterization mainly by methods of thermal analysis. The master thesis also uses method of rheology to determine the gelatinization time, method of TG/DTA do analyse the exo and endothermic effects during heating, the method of FT-IR to quickly determine the composition of samples, method of XRD to analyze phase composition of the samples and the method of SEM to observe the topography of the samples. MgO is used as a gelling agent, reactive alimina is used as a filler.
