Heating element cesium and platinum
WebMetallurgically, cesium forms alloys with the other alkali metals and gold and amalgamates with mercury. It does not alloy with cobalt, iron, molybdenum, nickel, platinum, tantalum, or tungsten at temperatures below 650° C (Burt, 1993, p. 759). Cesium also forms photosensitive intermetallic compounds with antimony, gallium, indium, and thorium. WebHeating elemental cesium and platinum together for two days at 973 K gives a dark red ionic compound that is 57.67% Cs and 42.33% Pt.

WebComparing the behaviour of these three metals in oxygen at high temperatures the authors conclude that platinum is the most, and palladium the least, volatile at temperatures up to 1200°C, whereas at 1300°C there is relatively little difference in the volatility of all three. The graph shown opposite illustrates these results.
