Phosphide powder usually refers to a binary compound composed of metal or nonmetal and phosphorus. Metal phosphides, such as calcium phosphide, zinc phosphide, aluminum phosphide, copper phosphide, etc. Non-metal phosphide does not interact with water and acid at room temperature. Most metal phosphides can be formed by the direct combination of metals and phosphorus. Ionic phosphides include alkali metals, alkaline earth metals, and phosphides of zinc, aluminum, etc. Metal-type phosphides include phosphides of most heavy metals. They are similar to intermetallic compounds in composition and appearance, and most of them are not easily decomposed by water or acid. Application of phosphide powder Ferrophosphorus (containing 23-29% phosphorus) is used to prepare high-strength steel. Containing 0.1-0.3% (alloyed) phosphorus can greatly improve the strength and corrosion resistance of steel. Ferrophosphorus is a by-product of elemental phosphorous produced by the electric furnace method. General commercial ferrophosphorus also contains a small amount of silicon, chromium, alum and other impurities. Magnesium phosphide releases half its mass of phosphine in moist air. Aluminum phosphide also releases highly toxic phosphine in humid air, and is therefore used as a grain fumigant. Copper phosphide is used as a deoxidizer. Gallium phosphide is used as a semiconductor.
