ZnCo 2 O 4 whiskers 2-5 µ m in diameter and up to 50 µ m in length, retaining their composition and shape up to 800 ° C, are prepared via decomposition of the mixed oxalate Zn 1/3 Co 2/3 C 2 O 4 · 2H 2 O in air and are characterized using chemical analysis, x-ray diffraction, IR spectroscopy, and scanning electron microscopy.
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.
