A Crucible is a ceramic, graphite or metal container in which metals or other substances may be melted or subjected to very high temperatures. A Platinum Crucible is a dish made (usually of pure platinum). Due to the special properties of the Platinum Metal, this enables the platinum crucible to be used for high temperature chemical reactions.
Because the melting point of Platinum is 1768 Degrees C, the Platinum Crucible can be heated to extremely high temperatures without having to worry about the crucible melting.
Types of Platinum Crucible
Typically, most Pt Crucibles are made of an extremely high grade of 99.95% platinum. Quite often however, the crucibles are made from an alloy of Platinum and Iridium (Pt/Ir) or even Platinum and Gold (Pt/Au).
The Platinum Alloy used to manufacture the crucible is usually dependent on the specific properties required for any specific application. Iridium Crucibles would be used for single crystal growing and should only be used under inert conditions, whereas a pure platinum crucible could be used for testing of pharmaceuticals and can be used in oxidising conditions.
