PLATINUM
A heavy gray-white, malleable metal, platinum is extremely rare, with the result that it is
significantly more valuable than gold. Like gold, platinum is resistant to tarnish and
corrosion. Used in a variety of technological processes and applications, platinum is a
highly effective catalyst; demand for this metal increased markedly with the advent of
catalytic converters, installed to reduce pollution from internal combustion engines.
