Melting Material point or Material properties Possible applications range [° C] Pt 1769 High thermal and chemical Laboratory apparatus such as stability. Platinum in various crucibles and dishes which are purities. only exposed to low mechanical stresses. Pt-DPH 1769 The finely dispersed oxide Laboratory equipment and particles in platinum and platinum structural components which are PtAu 95/5-DPH 1675 - 1745 alloys significantly increase the subject to high mechanical mechanical strength and stresses at high temperatures. PtRh 90/10-DPH 1840 - 1870 corrosion resistance.
PtIr 97/3 1772 - 1773 The mechanical strength, thermal Laboratory apparatus or structural and corrosion resistance become components which are exposed PtIr 90/10 1780 - 1800 greater with increasing iridium to severe mechanical, thermal content. Platinum Iridium alloys and corrosive effects. PtIr 80/20 1830 - 1855 suffer from increased weight loss in oxidizing atmosphere.
PtRh 90/10 1840 - 1870 The mechanical strength, thermal Heavy duty laboratory equipment, and corrosion resistance become electrodes, glass fibre bushings PtRh 80/20 1870 - 1910 greater with increasing rhodium and lining materials for content. An advantage of the components to contain molten platinum-rhodium alloys is that glass. only a minimal weight loss occurs even in oxidizing atmosphere.
Platilab 11 Small quantities of platinum group Laboratory apparatures or metals have been added to high structural components which are purity platinum, in order to obtain exposed to severe mechanical, a finer crystal structure for better thermal and corrosive effects. chemical and mechanical characteristics.
PtAu 95/5 1675 - 1745 The gold content reduces the These properties predestine PtAu wetting by glass melts so that the 95/5 as the material for apparatus glass can be easily removed after for the preparation of samples for solidification without leaving any X-ray fluorescence analysis residues. The mechanical (XRF). strength is also increased and the tendency to recrystallization reduced.
