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.

Roman numerals: for example the word "six" in the clue might be used to indicate the letters VI; The name of a chemical element may be used to signify its symbol; e.g., W for tungsten; The days of the week; e.g., TH for Thursday; Country codes; e.g., "Switzerland" can indicate the letters CH; ICAO spelling alphabet: where Mike signifies M and ...
Not all of these metals are found in all white metal alloys. Metals are mixed to achieve a desired goal or need. Metals are mixed to achieve a desired goal or need. As an example, a base metal for jewellery needs to be castable , polishable , have good flow characteristics, have the ability to cast fine detail without an excessive amount of ...
Zinc is bluish-white and lustrous, [9] though most common commercial grades of the metal have a dull finish. [10] Zinc is also referred to in nonscientific contexts as spelter. [11] Cadmium is soft, malleable, ductile, and with a bluish-white color. Mercury is a liquid, heavy, silvery-white metal.
An alloy of 96% zinc and 4% aluminium is used to make stamping dies for low production run applications for which ferrous metal dies would be too expensive. [140] For building facades, roofing, and other applications for sheet metal formed by deep drawing , roll forming , or bending , zinc alloys with titanium and copper are used. [ 141 ]
It is a blue black solid that adopts the fluorite structure. [12] A sesquioxide, Ir 2 O 3, has been described as a blue-black powder, which is oxidized to IrO 2 by HNO 3. [24] The corresponding disulfides, diselenides, sesquisulfides, and sesquiselenides are known, as well as IrS 3. [12] Binary trihalides, IrX 3, are known for all of the ...
Celestine (the IMA-accepted name) [6] or celestite [1] [7] [a] is a mineral consisting of strontium sulfate (Sr S O 4). The mineral is named for its occasional delicate blue color. Celestine and the carbonate mineral strontianite are the principal sources of the element strontium, commonly used in fireworks and in various metal alloys.
