As a metallurgist familiar with both tantalum and her sister metal niobium (they are usually found together), I can say that tantalum is the foundation of modern electrolytic capacitors (excluding the huge aluminum capacitors for power applications). It's unlikely that you'd be reading this now if tantalum didn't exist. Physical characteristics? It's kind of green. It's heavy (16.6 g/cc) . It's a getter, meaning it sucks up oxygen like a sponge. (This is why it makes good capacitors; tantalum pentoxide is a very good dielectric film -- but only if you know how to grow a smooth one.) A wonderful metal in some respects, diabolical in others.

What is a good replacement for coltan?
That's tough, nobium and tantalum have such special characteristics that it isn't easy to find a replacement. Coltan is the colloquial African name for columbite - tantalite, a dull black, metallic ore from which the elements niobium (formerly "columbium") and tantalum are extracted.

Is tantalum magnetic?
Tantalum itself is not magnetic (does not generate the magnetic field); however, it is a paramagnetic material...meaning it will react to a magnetic field. see Paramagnetic
