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.

... existence of a conflagration. Such are sometimes operated by a compound bar thermostat (see Thermostat), which on a given elevation of temperature closes a circuit and rings an electric bell. Sometimes the expansion of a column of mercury when heated is used. This, by coming in contact with one or two platinum points, completes a circuit, and ...

... was particularly nice to be hospitably received in my sister's house, where I hoped to revive my somewhat exhausted means of travel. In this hope I reckoned chiefly upon the sale of a snuff-box presented to me by a friend, which I had secret reasons to suppose was made of platinum. To this I could add a gold signet-ring, given me by my friend Apel for composing the overture to his Columbus. The value of the snuff-box unfortunately proved to be entirely imaginary; but by pawning these two jewels, the only ones I had left, ...

One of these was the use of platinum gauze by Kitson. He produced an apparatus similar to the oil-spray lamp, on a small and more delicate scale. The hot blue flame was not very luminous and he attempted to obtain light by heating a mantle of fine platinum gauze. Although these mantles emitted a brilliant light for a few hours, ...

He rejected the principle of the Voltaic arc involved in the Brush patent then in use, by which the electric current was passed through a strip of platinum or other metal that requires a high temperature to melt, because in practice it was found that in fact, owing to the difficulty of regulating the flow of the electric current, the medium did often melt. He therefore sought for a medium that should ...

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 up the various complex unstable compounds into ...
