Tantalum Carbide Nanoparticles and Their Applications

Tantalum carbides form a family of binary chemical compounds of tantalum and carbon with the empirical formula TaCx, where x usually varies between 0.4 and 1. Tantalum carbides are extremely hard, brittle, refractory ceramic materials with metallic electrical conductivity. They appear as brown-gray powders, which are usually processed by sintering.
TaC (Tantalum Carbide) Nanoparticles (99.5+%, 950 nm, Cubic) have high purity, small diameters, even distribution, large specific surface area, high surface activity and low apparent density, as well as the excellent mechanics, electricity and chemical properties. Tantalum carbide nanoparticles have higher hardness, melting point, wear resistance and low thermal expansion coefficient and high temperature elevated strength. Nanoparticles of tantalum carbides exhibit superior mechanical properties and their tailored particle size and shape is for improved sintering and densification.
Tantalum carbide nanoparticles are suitable to cut a variety of materials such as gray cast iron, ductile nodular iron, stainless steel, nickel-based alloys. Tantalum carbide nanoparticles coatings are used industrially for wear protection of steel moulds employed in injection cast molding of aluminum and aluminum alloys.
High speed steel tools for machining are coated with tantalum carbide nanoparticles and are used in high speed milling machine. Tantalum carbide nanoparticles are desirable for market applications such applications as boost rocket motor nozzles that require high thermal shock resistance. In the commercial sectors tantalum carbide nanoparticles have potential application as a material used for cutting tools and wear parts.
Tantalum carbide nanoparticles can be used in biomedical, corrosion, aerospace and electrotechnology applications. Tantalum carbide nanoparticles stand as a candidate material for next generation thermal heat protection, space aircrafts, automotive wear resistant liners, and propulsion-exposed components.
Due to their optical, electronic and magnetic properties tantalum carbide nanoparticles have been used for optical coatings, electronic contacts and diffusion barriers.

Cadmium Sulfide Nanopowder and Its Applications

Cadmium sulfide is the inorganic compound with the formula CdS. Cadmium sulfide is a yellow solid. It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite. As a compound that is easy to isolate and purify, cadmium sulfide the principal source of cadmium for all commercial applications. Its vivid yellow color led to its adoption as a pigment for the yellow paint "cadmium yellow" in the 18th century. Cadmium Sulfide Nano Powder, CdS (99.9+%, 20 nm)  shows unique physical, chemical and structural properties from the bulk. The melting point, electronic absorption spectra, band gap energy crystal structure, and other properties of cadmium sulfide nanoparticles are affected by size. Thus, cadmium sulfide on the whole is an attractive system for practicing synthetic chemistry for nanocrystals and for understanding the chemistry, growth history of nanomaterials and also for various technical applications. Colloidal dispersions of ...
