Phosphide Powder Classification
Alkali metals include alkaline earth and metals such as zinc, aluminum, and otherphosphates. You can think of these compounds as derivatives phosphine. They are composed of hydrogen atoms that have been replaced by metals with equal equivalence. Acids can decompose almost all ionicphosphates. Example: Calcium phosphide Ca3P2 can be easily dissolved in water and formed phosphide (and hydroxide) by reacting with it. Zinc-phosphide Zn3P2 reacts with water slowly, but with acid quickly.
These phosphates contain most heavy metals. Phosphates are similar in appearance and composition to metal intercompounds. Most are difficult to break down by acid or water.
Ferric phosphor is used in the preparation of high-strength, but not very expensive steel. Steel with 0.1-0.3% (alloyed), phosphorus can greatly improve its strength and resist corrosion. One phosphor can be produced in an electric furnace. Ferric phosphor comes from this by-product. In general, commercial ferricphosphor, there is a tiny amount of silica, chromium and other impurities.
Iridium phosphide has a very high chemical stability and hardness, so it is often used to make pens.
Magnesium-phosphide emits half of its phosphine when it is moistened.
The aluminum phosphide, which also emits highly toxic phosphine when moistened air is present in the environment, can also be used to fumigant grains.
Copper phosphide serves as a catalyst.
The semiconductor is made from a phosphating grains.
It’s a reddish-brown crystal or graygranular material, with a melting point around 1600 and a relative density of 2.51 It is insoluble and insoluble with acid; it can be prepared by heating aluminum, carbon or reducing calcium phosphate. This is useful for the production of phosphine as well as signal bombs, fireworks and other explosives. Zinc Phosphide (dark gray) is an incombustible powder, with a strong odor. The melting point for zinc phosphide exceeds 420. Pesticides that contain zinc phosphide and red phosphorus (acting at 550) are used to kill rats and mice. Aluminum phosphide can be described as a grey-yellow, powdered crystal. It does not melt nor sublimate. The relative density of aluminum phosphide is 2.85 and its ignition temperature is 100. It’s made from aluminum powder and red-phosphorus. The product is activated by electric current, flame or flame at 650. To kill insects, aluminum phosphide must be dried and stored.
The red, highly toxic crystal chemically known as Na3P is formed when water evaporates and releases toxic, flammable gases. As a phosphating ingredient to make pesticides and phosphine. Chemical reactions are used to produce red phosphorus as well as metallic sodium.
A colorless, toxic and flammable liquefied compressed natural gas, called phosphorine, is kept in cylinders. Phosphine’s storage pressure equals 522psig, or 70oF of its vapor. The gas weighs more than air and smells like stinky fish. If traces of other phosphorus hydroides like ethophosphate can be found, spontaneous combustion may occur. Phosphine should be treated as an extremely toxic gas that is spontaneously inflammable. Phosphine may cause damage to the liver, heart, lung, and stomach.
