General Information about Tantalum                                      Tantalum  is a chemical element with symbol Ta and atomic number 73. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of  tantalum makes it a valuable substance for laboratory equipment and a substitute for platinum. Tantalum Nanoparticles/Nanopowder and Their Applications When Tantalum nanoparticles/nanopowder are added to other metals, these  nanoparticles/nanopowder  impart a number of benefits.  Tantalum nanoparticles/nanopowder  help to obtain alloys with high melting points, good ductility and high overall strength. Tantalum nanoparticles/nanopowder are bio-inert. So Tantalum nanoparticles/nanopowder can be used ...

Tantalum carbides form a family of binary chemical compounds of  tantalum  and carbon with the empirical formula TaC x , 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 s...

Tantalum oxide, also known as tantalum(V) oxide, is the inorganic compound with the formula Ta 2 O 5 . It is a white solid that is insoluble in all solvents but is attacked by strong bases and hydrofluoric acid.  Tantalum Oxide (Ta2O5) Sputtering Targets (Size:2'' ,Thickness:0.125'' , Purity: 99.99%)  is an inert material with a high refractive index and low absorption which makes it useful for coatings. It is also extensively used in the production of capacitors, due to its high dielectric constant. Tantalum oxide films are of interest for applications in high temperature resistance, anti-reflection coatings for solar cells, optical waveguide, oxygen sensors, and capacitor dielectric materials. In recent years they have received increasing attention as an alternative dielectric to replace thin SiO, films for storage capacitors in very large-scale-integrated memory cells and as gate insulators in metal-oxide-semiconductor devices. Tantalum oxide films can be formed...

- 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. Posted by Direniş ÇA...
