TANTALUM
First of all, where does the name of this metal come from?
The metal, grey and hard, was named after Tantalus, a hero of
Greek mythology.
Tantalus was the son of Zeus and the nymph Pluto and father
of Niobe.
Tantalus was severely punished because he revealed the
secret
of Zeus. He was plunged up to the chin in water with the
fruit hanging over his head. But both water and fruit withdraw
from him, whenever he tried to reach for them.
In the early nineteenth century Ekeberg, a Swedish scientist,
suffered about as much as Tantalus himself when he discovered
a new element in some minerals but could not get it pure. The
first chemist who got it in a comparatively pure state was
Berzelius. But even he failed.
It was really his follower Henry Rose who finally got pure
tantalum after he had studied its properties for almost fifteen
years.
In fact, even now it is difficult to get pure tantalum.
What about the uses of this rare metal? Where is it applied? It
has important uses in medicine, to begin with. Surgeons fix up,
fractured bones and skulls and unite tissues with it. They, also,
use tantalum to replace muscles. And they knit together, sinews
with fine tantalum wire.
Doctors believe it possible to make use of tantalum in
surgery because it does not irritate tissues. And it does not
disrupt the functions of the body either.
