- n. Plural form of phosphide.
Sorry, no etymologies found.
It was originally believed that the impurities of the slowly formed acetylene, the phosphine in particular, acted as toxic agents upon the phylloxera; and therefore carbide containing an extra amount of decomposable phosphides was specially manufactured for the vine-growers.
In the earliest days of the acetylene industry, directly it was recognised that phosphine always accompanies crude acetylene from the generator, it was believed that unless the proportion were strictly limited by decomposing only a carbide practically free from phosphides, the crude acetylene might exhibit spontaneously inflammable properties.
The precise way in which these organic bodies are formed from the phosphides and sulphides of calcium carbide is not thoroughly understood; but the system of generation employed, and the temperature obtaining in the apparatus, have much to do with their production; for the proportion of the total phosphorus and sulphur found in the crude gas which exists as "compounds" tends to be greater as the generating plant yields a higher temperature.
In California, aluminum and magnesium phosphides already were designated as "restricted-use materials," meaning you need a permit from a county agricultural commissioner before using them, according to Lea Brooks, assistant director of communications for the state Department of Pesticide Regulation.
Yellow-green LEDs use arsenide-phosphides, materials that are much more developed for use as LEDs than nitride-based diodes that are required for blue-green light emission.
"Processes in which the slag is smelted with charcoal, to reduce phosphates to phosphides, treated with acid, and the phosphuretted hydrogen burnt to phosphoric acid; and,
