While less rhodium than ruthenium and palladium is formed (around 3.6% yield), the mixture of fission products still contains a significant amount of this metal. Due to the high prices of ruthenium, rhodium , and palladium, some work has been done on the separation of these metals to enable them to be used at a later date.
Physical properties. Osmium, remelted pellet. Osmium is a hard, brittle, blue-gray metal, and the densest stable element —about twice as dense as lead. The density of osmium is slightly greater than that of iridium; the two are so similar (22.587 versus 22.562 g/cm 3 at 20 °C) that each was at one time considered to be the densest element.
Rhenium. hexagonal close-packed (hcp) ( hP2) Rhenium is a chemical element; it has symbol Re and atomic number 75. It is a silvery-gray, heavy, third-row transition metal in group 7 of the periodic table.

Californium-252 has a number of specialized uses as a strong neutron emitter; it produces 139 million neutrons per microgram per minute. [27] This property makes it useful as a startup neutron source for some nuclear reactors [ 17 ] and as a portable (non-reactor based) neutron source for neutron activation analysis to detect trace amounts of ...
The best known precious metals are the coinage metals, which are gold and silver. Although both have industrial uses, they are better known for their uses in art, jewelry, and coinage. Other precious metals include the platinum group metals: ruthenium, rhodium, palladium, osmium, iridium, and platinum, of which platinum is the most widely ...
The 2000s commodities boom or the commodities super cycle[ 1] was the rise of many physical commodity prices (such as those of food, oil, metals, chemicals and fuels) during the early 21st century (2000–2014), [ 2] following the Great Commodities Depression of the 1980s and 1990s. The boom was largely due to the rising demand from emerging ...
