General description

The structure of tantalum is body centered cubic (BCC) metal. It is a refractory metal; stable up to very high temperatures. Tantalum is ductile at room temperature and moderately ductile at cryogenic temperatures. Compton profile of highly pure thin elemental foil of tantalum was investigated using IGP type coaxial photon detector.1

Biomedical Implant Devices Fabricated from Low Young’s Modulus Titanium Alloys Demonstrating High Mechanical Biocompatibility

Biomedical implants are essentially foreign substances within the human body that must survive many years’ exposure to demanding mechanical and physiological conditions. Despite these challenges, metal implants have been widely used to substitute for or rebuild hard tissues such as bones and teeth.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
