Chromium carbide micro-whiskers dataset: Morphologies with scanning and transmission electronic microscopy

Chromium carbide exhibits a superior set of mechanical properties and chemical stabilities and is widely used in various engineering applications. Here, micro-whiskers of the Cr₂O₃ were successfully prepared using a carbothermal reduction method with high energy milling and liquid phase catalysis. The whiskers growth was observed with scanning electron microscopy and field emission gun transmission electron microscopy. This dataset shows all kinds of morphologies of the Cr₂O₃ whiskers during the growth stage, including agglomerated, pointed, and non-whiskered shapes, which are products of the mixture of Cr₂O₃:C = 1:5 or 1:8 or 1:10 under different temperatures and duration time. These data provide important additional information different from the source article but complement it with some negative but indicative and instructive data. Experimental scientists who want to investigate the growth and strengthening of whiskers of Cr₂O₃ or others can refer to and benefit from these data, such as possible combinations of the experimental conditions which may lead to certain outcomes and guide the predictive design of future relevant research with similar materials system.
