Platinum   Listen
noun
Platinum  n.  (Chem.) A metallic element of atomic number 78, one of the noble metals, classed with silver and gold as a precious metal, occurring native or alloyed with other metals and also as the platinum arsenide (sperrylite). It is a heavy tin-white metal which is ductile and malleable, but very infusible (melting point 1772° C), and characterized by its resistance to strong chemical reagents. It is used for crucibles in laboratory operations, as a catalyst, in jewelry, for stills for sulphuric acid, rarely for coin, and in the form of foil and wire for many purposes. Specific gravity 21.5. Atomic weight 195.1. Symbol Pt. Formerly called platina.
Platinum black (Chem.), a soft, dull black powder, consisting of finely divided metallic platinum obtained by reduction and precipitation from its solutions. It absorbs oxygen to a high degree, and is employed as an oxidizer.
Platinum lamp (Elec.), a kind of incandescent lamp of which the luminous medium is platinum. See under Incandescent.
Platinum metals (Chem.), the group of metallic elements which in their chemical and physical properties resemble platinum. These consist of the light platinum group, viz., rhodium, ruthenium, and palladium, whose specific gravities are about 12; and the heavy platinum group, viz., osmium, iridium, and platinum, whose specific gravities are over 21.
Platinum sponge (Chem.), metallic platinum in a gray, porous, spongy form, obtained by reducing the double chloride of platinum and ammonium. It absorbs oxygen, hydrogen, and certain other gases, to a high degree, and is employed as an agent in oxidizing.

... European side of the Ural there is a deposit of copper sand-ore, extending over a district of 480 miles in length, by 280 in breadth. The mineral wealth of Asiatic Russia is far greater. It consists of copper ores; iron cropping out at the surface, gold and platinum. The Altai Mountains especially produce silver, and some gold, with lead and copper ores. The silver mines of this region were worked at a very early period, as is proved by the discovery of an excavation a thousand ...

... that his discovery was connected with the ring of Thoth. I had some remembrance of the trinket. It was a large and weighty circlet, made, not of gold, but of a rarer and heavier metal brought from the mines of Mount Harbal. Platinum, you call it. The ring had, I remembered, a hollow crystal set in it, in which some few drops of liquid might be stored. Now, the secret of Parmes could not have to do with the metal alone, for there were many rings of that metal in the Temple. Was it not more likely ...

... finest mineral districts in the world, but had it not been for the inexhaustible deposits of all the useful metals in its vicinity, it is probable a city would never have sprung up in such an inhospitable region. Between the Coppermine and Mackenzie Rivers gold and silver are abundant. Platinum and iridium are also common, and are exported from here to all parts of the world; they are in great demand by chemists and electricians. A rough population from all quarters has been attracted to the district, of which Bearville is the centre, and it would astonish ...

... crystals. Its empirical form is C23H40N2; it is probably volatile and is notable for its lack of oxygen. It differs from quinoidine in that it is inactive (?) and that in combination with platinum it retains less of this metal than does quinoidine. It differs from paricine in its proportion of hydrogen, and from berberine in containing more carbon. In the presence of sulphuric acid its solution assumes a yellow color, changing to wine-red ...

And (according to the Banker-poet, Rogers) the Duke of Wellington. That of Napoleon is said to have been made of platinum-wire, the work of a Pole who received his money and an order to quit Paris. The late Sir Robert Clifton (they say) tried its value with a Colt after placing it upon one of his coat-models or mannequins. It is easy to make these hauberks arrow-proof or sword-proof, even bullet-proof ...

The boy's heart leaped into a heightened tattoo and he bent eagerly forward with his lips parted.

But if the cylinder is exhausted and then filled with air which is passed slowly through a fine gauze of intensely heated platinum wire, so as to burn up all the floating dust particles, which are mainly organic, the light will pass through the cylinder without illuminating the interior, which, viewed laterally, will appear as if filled with a dense black cloud.

... imaginary living being, the protobion. To get this protobion the chemists summon a reagent known as a catalyser. The catalyser works its magic on the jelly mass. It sets up a wonderful reaction by its mere presence, without parting with any of its substance. Thus, if a bit of platinum which has this catalytic power is dropped into a vessel containing a mixture of oxygen and hydrogen, the two gases instantly unite and form water. A catalyser introduced in the primordial jelly liberates energy and gives the substance power to break ...
