Original abstract
In this paper the determination of chemical composition of advanced materials as nanoceramics using the microwave digestion and atomic absorbance spectroscopy is discussed. The technique of microwave-assisted digestion is used for preparation of the materials for analysis of chemical composition. The exact chemical composition is one of the most important parameters for prediction of material behavior even at severe reducing conditions and elevated temperatures. The method of microwave-assisted digestion was investigated very well in inorganic materials where the microwave heating dramatically improved the decomposition process and the reaction time was slow down from hours to minutes in many cases. The decomposition of ceramics is more difficult due to their high stability at hydrothermal conditions. The decomposition of ceramic materials with different solvents and additives was studied.

V této práci je diskutováno určení přesného chemického složení pokročilých materiálů jako je nanokerarmika pomocí mikrovnného rozkladu a atotmové absorbční spektroskopie. Pro přípravu vzorků na analýzu byla použita metoda rozkladu podporovaného mikrovlnným polem. Pro aplikace materiálu je určení přesného chemického složení jedním z důležitých parametrů. Použtím mikrovlnného rozkladu pro anorganické materiály vede v mnoha případech ke snížení reakční doby z hodin na minuty. Rozklady keramických materiálů jsou složitější díky jejich vysoké stabilitě i za hydrotermálních podmínek, proto je jedním z cílu práce studovat rozklady těchto materiálů v různých solventech a za přítomnosti různých aditiv.
