- Silicon carbide is a compound of silicon and carbon, also known as carborundum .
- Silicon carbide nanopowder has larger specific surface area, high purity, and narrow range particle size distribution
- Silicon carbide has smaller thermal expansion coefficient, better abrasion resistance, chemical stability,and high thermal conductivity
- Silicon carbide’s mechanical strength is higher than the corundum
- Silicon carbide nanopowder is a semiconductor and resistant to oxidation in high temperature.
- In the arts, silicon carbide is a popular abrasive in modern lapidary due to the durability and low cost of the material.
- In manufacturing, it is used for its hardness in abrasive machining processes such as grinding, honing, water-jet cutting and sandblasting.
- Particles of silicon carbide are laminated to paper to create sandpapers and the grip tape on skateboards.

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.
