INTERESTING FACTS ABOUT TANTALUM ELEMENT



-Tantalum is a chemical element with symbol Ta and atomic number 73.
-Tantalum is part of the refractory metals group, which are widely used as minor components in alloys.
- Tantalum is dark (blue-gray),dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity.
- Tantalum is a shiny, silvery metal which is soft when is pure.
- Tantalum is almost immune to chemical attack at temperatures below 150 C.
- Tantalum is virtually resistant to corrosion due to an oxide film on its surface.
- Tantalum finds use in four areas: high-temperature applications, such as aircraft engines; electrical devices, such as capacitors; sirurgical impants and handling corrosive chemicals.
- Because tantalum oxide is very insoluble, there is almost no tantalum to be found in natural waters.
- Tantalum has no known biological role. It is non-toxic.
- Tantalum has a melting point exceeded only by tungsten and rhenium.

Boron Carbide Nanoparticles and Their Applications

Boron carbide  which has the chemical formula of B 4 C is one of the hardest materials among the ceramics materials after diamond and boron nitride. In addition to its hardness, it has high thermal stability, low density, chemical inertness and neutron capture property. At temperature above 1200  o C, its hardness exceeds that of the diamond. Thus, it is a crucial material for high technology applications such as abrasive for polishing and grinding media, ceramic amour applications for personal purpose and equipment, blasting nozzles, ceramic bearings, semiconductor applications for dielectric barriers, medical and nuclear applications. B4C (Boron Carbide) Nanoparticles (99.5+%, 40-60nm, Hexagonal)  show an outstanding hardness among the ceramic materials. Therefore, boron carbide nanoparticles are a suitable material for many high performance applications. Boron carbide nanoparticles can be used as polishing, lapping and grinding material for hard mater...

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 ...
