Abstract:ZrB 2 powders were synthesised by microwave heating using the sol-gel method for precursor with eight C 6 H 14 O 6 (ZrOCl 2 •8H 2 O), boric acid (H 3 BO 3 ), citric acid (I), and mannitol (as raw materials). The results show that the temperature at which the ZrB 2 powder is completely synthesised by microwave heating is 1400°C, which is 300°C lower than the traditional way. XRD and SEM were used to characterise the phase composition and morphology of the powders. In addition, the effects of raw material ratios… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
