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 factors for prediction of material behavior even at severe reducing conditions and elevated temperatures. The method of microwave-assisted digestion was deeply studied 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.
