# Which metals with high density do not react with mercury?

I would like to know the highest density material between 10-17 g/mol range that is less than mercury and does not react with mercury.

Also would I like to know the highest density metal that is in solid form naturally.

Which ones are easily available and are highly dense?

• 1) Iron is not smelted by mercury (it's ~8 g/ml). Not sure about 10-17 g/ml. 2) The mosts are Iridium and Osmium. The most easily available is lead, though it requires some caution when used. – permeakra Jul 9 '14 at 7:30

Here is a link to a chart of all the elements in the Periodic table and their densities. Iridium at $22.65~\mathrm{g/cm^3}$ is the densest of all the elements with Osmium a close second at $22.61~\mathrm{g/cm^3}$. Sigma-Aldrich sells both of these metals (Iridium \$126.50 for 0.5 gram; Osmium \$195 for 1 gram).
Mercury has a density of $13.534~\mathrm{g/cm^3}$. It sounds like you're asking for something with a density right below mercury that doesn't react with mercury. Rhodium at $12.45~\mathrm{g/cm^3}$ is probably the most readily available element with a density less than mercury. As to rhodium's reaction with mercury, an alloy is formed at 175 C. If you're working at room temperature, especially for shorter periods of time (like hours) you'd probably be OK, but it really depends on your specific application.
• Thanks for the helpful reply. I see rhodium is highly expensive Rhodium costs Price 1g= $70,10g=$490 > Yeah,Osmium is also more dense. Oxidization on air- Thanks for the info. – user7063 Jul 9 '14 at 16:38
