What is phosphating powder?

Phosphating powder usually refers to a binary compound composed of metal or nonmetal and phosphorus. Metal phosphides, such as calcium phosphide, zinc phosphide, aluminium phosphide, copper phosphide, etc.

Non-metallic phosphides do not interact with water and acids at room temperature. Most metal phosphides can be formed by the direct combination of metal and phosphorus.

Ionic phosphides include alkali metals, alkaline earth metals, zinc, aluminium and other phosphides.

Metallic phosphides include the phosphides of most heavy metals. They are similar to intermetallic compounds in composition and appearance, and most are not easily decomposed by water or acid.

Application of phosphating 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 the production of elemental phosphorus 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 the humid air.

Aluminium phosphide also releases highly toxic phosphine in moist air and is therefore used as a grain fumigant.

Copper phosphide is used as a deoxidizer.

Gallium phosphide is used as a semiconductor.
