| Thermal analysis of ternary Al-BN-SiC batch aimed for the production of nanomodified functional Al2O3-BN-SiC ceramics and the analysis of binary systems and individual compounds forming the above system were performed. It was shown that powders dispersion and samples pretreatment (pressing, heating in air, and vacuum annealing) affect thermal behavior of the samples. The nature of endothermic and exothermic effects as well as peculiarities of weight changes during heating-cooling cycles are discussed. The information for ternary system samples is compared with the data obtained for samples modified by nano-sized zirconia powder. As a result of the study, the conclusion on the suitability of the chosen composition for themanufacturing of nanomodified functional ceramics is stated. |
