Application areas | Typical applications are crucibles and other equipment for processing special optical glasses, as the alloying elements can cause an unacceptable discoloration of the glass. For similar reasons, crucibles of Pt DPH are used in the manufacture of many single crystals by the Czochralski and Bridgman processes. Particularly in periods of high rhodium prices, Pt DPH is also used as a lining for refractory components. In this case, the refractory takes on the main load-bearing function. A further application is in thermocouple thimbles for use in glass melts containing sulphur. The sulphur in the glass can react with rhodium in Pt-Rh alloys leading to the formation of a eutectic that melts at 925°C, thus destroying the thimble. In contrast, thimbles of Pt DPH can be used in similar environments at temperatures exceeding 1200°C. |
