Platinum Crucible

Standard shape crucible made from 99.95% pure Platinum and Platinum alloys are manufactured to endure harsh use with their thicker base and lighter wall construction.

…hydrofluoric, hydroiodic, nitric, selenic, and sulfuric, and to oxidation at high temperatures. Crucible lids of platinum can be cleaned by boiling in a suitable solvent.For the removal of substances which have alloyed with the surface, scour with alumina powder. Synonyms: crucibles

Made from 99.95% pure platinum and platinum alloys, these crucibles have thicker bases and lighter walls that help them endure harsh use. “Non-wetting” 5% gold-platinum alloy crucibles are also available for use in the glass, ceramic and cement industries.
