Because of their hardness, high melting points and high temperature stability PGMs are the perfect coating for industrial crucibles where high temperatures are necessary to produce chemicals and synthetics with the utmost efficiency.

The high temperature stability, melting points and corrosion resistance of platinum, rhodium, iridium, ruthenium and their alloys allow for higher temperatures to be achieved in crucibles, a key factor in any chemical process.

The "nobility" of PGMs is also crucial. High purity conditions are required for these processes and PGMs' high temperature stability means that they do not contaminate the products being fabricated.

Products produced in such ways include:
Artificial silk, Crystals, Glass, Glass fibre
