For most electrical engineers, the only time you hear about tantalum is in regards to capacitors. So this leads many of us to believe that is the only reason for mining the ore. Truth Tantalum has high biocompatibility, making it suitable for medical implants. However, mechanically it is not very strong, compared to other metals.

Answer (1 of 3): Both Tantalum and Titanium are used for orthopaedic implants. Both primarily for biocompatibility. Titanium actually has a modulus of elasticity that is fairly close to that of bone (ie it is not significantly stiffer), and thus does not cause stress shielding. This is advantageo...

Polarized capacitors are capacitors with tantalum and aluminum electrolytes covered by an oxide layer. These capacitor types need polarity markings. If the capacitors do not have the markings, the component and the entire circuit board may damage. You can determine the polarity of a capacitor if it has signs like "+" and "-.".

The MnO 2 cathode has a property that significantly contributes to tantalum capacitor reliability. Defects in the Ta 2 O 5 dielectric cause local heating at the defect site during capacitor operation, which changes the nearby MnO 2 to Mn 2 O 5 — a non-conductive phase of manganese oxide. This non-conductive site serves to remove that portion of the capacitor …
