The present work shows two approaches to obtain titanium diboride (TiB 2 ). The traditional high-temperature carbothermal reduction synthesis is performed using boron carbide (B 4 C) as boron source. The direct mechanochemical synthesis is accomplished in a planetary mill using boron and titanium powders as reagents. The synthesis reaction proceeds by explosive mechanism after 90 min of intense mechanical treatment. Here using SEM, XRD and analytical chemical methods, we examine the morphological properties of the products obtained by both synthesis methods. These properties are responsible for the sinterability of the product and determine the possibility to produce dense bodies by the methods of the powder metallurgy.
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.
