Typical Chemical Analysis

 Experts Review:

Jules L. Routbort (Argonne National Laboratory, Argonne, USA)
Tantalum Nanoparticles is a rare, shiny, gray, dense metal. It is highly ductile and can be drawn into a thin wire. Its chemical properties are very similar to those of niobium. Tantalum is highly corrosion resistant due to the formation of an oxide film. It is an excellent conductor of heat and electricity. The metal has a melting point exceeded only by tungsten and rhenium. Tantalum is one of the five major refractory metals (metals with very high resistance to heat and wear). The other refectory metals are tungsten, molybdenum, rhenium and niobium. Tantalum is considered to be non-toxic.

Tantalum Nanoparticles is mostly used in electronics applications for capacitors and high power resistors. It is also used to make alloys to increase strength, ductility and corrosion resistance. The metal is used in dental and surgical instruments and implants, as it causes no immune response.

Tantalum Nanoparticles: The properties of tantalum nanopowder is similar to gold nanoparticles, but are far more cost-effective, and thus, well-positioned to replace gold in regenerative medicine for labeling and tracking of cell grafts through x-ray-based imaging. However, the amount of tantalum nanoparticles that can be taken up by stem cells is not enough to make individual cells visible in x-ray images.

Tantalum Nanoparticles: Nanoscale tantalum powder has been widely studied for a variety of applications. For example, superfine and pliable tantalum powders were needed to improve the quality or reduce package size of capacitors. Reduction in package size allows designers to add higher-capacitance-value parts to existing circuits or to use smaller package size to further miniaturize their circuits.

Tantalum Nanoparticles: Porous tantalum also facilitates the in growth of soft tissue, including the formation of blood vessels that were found to assemble on the surface and within the structure of the porous tantalum. Also, since tantalum is strongly radiopaque due its high atomic number, this property is widely employed for marking in orthopedics and in endovascular medical devices. Another important development was the production of nanoparticles based on tantalum. These particles have been shown to be superior to iodinated contrast agents for blood pool imaging applications due to their longer circulation time.
