If you want to know where the data comes from for any particular property, then select that property. You'll see graphs for the properties as well. The name iridium is appropriate, for its salts are highly coloured.
Iridium is white, similar to platinum, but with a slight yellowish cast.
It is very hard and brittle, making it very hard to machine, form, or work. Strange Matter cartoon included by kind permission of Nick Kim at the University of Waikato , New Zealand. All rights reserved.
