- Tantalum carbides form a family of binary chemical compounds of tantalum and carbon
- Tantalcarbide is a natural form of tantalum carbide.
- Tantalum carbide is cubic, extremely rare mineral.
- Tantalum carbide appear as brown-gray powders, which are usually processed by sintering.
- The melting points of tantalum carbides peak at about 3880 °C depending on the purity and measurement conditions
- Tantalum carbide is an extremely hard (Mohs hardess 9-10) refractory ceramic material, commercially used in tool bits for cutting tools.
- Tantalum carbide is sometimes used as a fine-crystalline additive to tungsten carbide alloys.

Carbon nanotubes (CNTs) have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.
