Nanoparticle research has discovered unexpected behavior of the basic elements when their atomic and molecular properties are altered. These altered properties have made valuable contributions in fields such as biomedicine, pharmaceuticals, electronics and ceramics. This article will look into the properties and applications of tantalum carbide.
Tantalum carbide (TaC) nanoparticles exhibit hardness which is greater than that of diamond. These particles are produced by the process of sintering. Another distinction associated with tantalum carbide is that it is a stoichiometric binary compound having the highest melting and boiling points. Tantalum belongs to Block D, Period 6 while carbon belongs to Block P, Period 2 of the periodic table.
The following tables list the chemical properties of tantalum carbide.
