Abstract
Bakalářská práce studovala chemické reakce typu solution combustion synthesis. Cílem práce bylo porozumění tomuto typu reakcí vzhledem k možnosti jejich využití ve výuce chemie. V literatuře byl zjištěn současný stav řešené problematiky. Bylo odzkoušeno šest reaktantů ve formě paliva pro dusičnan železitý. Byla studována stechiometrie a termodynamika probíhajících reakcí. Byly pozorovány vlivy dodržení stechiometrie, způsobu iniciace a hmotnostních relací na průběh reakcí a vzniklé produkty. Pro hodnocení byly využity přístrojové techniky včetně metod TGA, DSC a SEM. Práce je bohatě dokumentována fotografiemi a videozáznamy.
The bachelor thesis studied chemical reactions solution combustion synthesis. The aim of this work was to understand this type of reactions in view of their use in chemistry teaching. The current state of the solved problem was found in the literature. Six reactants in the form of fuel for ferric nitrate were tested. Stoichiometry and thermodynamics of ongoing reactions were studied. The effects of stoichiometry, initiation and mass relations on the course of reactions and products were observed. Instrumentation techniques including TGA, DSC and SEM methods were used for evaluation. The bachelor thesis is richly documented with photographs and videos.
