Iridium Crucible
Some of the most intriguing items that we produce are Iridium crucibles. They are able to withstand heavy thermocycling at extremely high temperatures. They are used in the manufacturing of crystals for the Telecom industry.

A bottom view of an Iridium crucible for the Telecom industry. All standard sized crucibles are available (30cc to > 6000cc). Wall thickness 4.0mm to below 1.0mm (0.157” to 0.04”).

Iridium Feeder
This chamber has been fabricated from Iridium sheets. Over many years, Johnson Matthey has developed methods of working iridium into component form.

Iridium Feeder
Iridium is the second densest of all elements.

Iridium Feeder
Iridium has a melting temperature of 2446°C (4435°F), which is exceeded only by the refractory group metals.

Iridium Feeder
Iridium exhibits excellent high temperature properties and mechanical strength. It can be used in certain applications, unprotected, in air temperatures exceeding 2000°C (3632°F). At these temperatures it also shows outstanding resistance to a variety of salts and oxides.

Iridium Feeder
Iridium is unaffected by common mineral acids and aqua regia.

Iridium Feeder
Iridium is an obvious choice for a whole range of high temperature applications. However, its high degree of stiffness and resistance to deformation render its fabrication into complex components difficult. Over many years, Johnson Matthey has developed methods of working iridium into component form.
