Ferrophosphorus is a ferroalloy, an alloy of iron and phosphorus. It contains high proportion of iron phosphides, Fe 2 P and Fe 3 P. Its CAS number is 8049-19-2. The usual grades contain either 18 or 25% of phosphorus. [1] It is a gray solid material with melting point between 1050-1100 °C. It may liberate phosphine in contact with water. Very ...

Lithium iron phosphate or lithium ferro-phosphate (LFP) is an inorganic compound with the formula LiFePO 4. It is a gray, red-grey, brown or black solid that is insoluble in water. The material has attracted attention as a component of lithium iron phosphate batteries, [1] a type of Li-ion battery. [2]
[4] [PdCl 2] n + 2 n PPh 3 → n PdCl 2 (PPh 3) 2. The first reported phosphine complexes were cis- and trans-PtCl 2 (PEt 3) 2 reported by Cahours and Gal in 1870. [5] Often the phosphine serves both as a ligand and as a reductant. This property is illustrated by the synthesis of many platinum-metal complexes of triphenylphosphine: [6]
Phosphogypsum is a by-product from the production of phosphoric acid by treating phosphate ore with sulfuric acid according to the following reaction: Ca 5 (PO 4) 3 X + 5 H 2 SO 4 + 10 H 2 O → 3 H 3 PO 4 + 5 (CaSO 4 · 2 H 2 O) + HX where X may include OH, F, Cl, or Br
Iron phosphide is a chemical compound of iron and phosphorus, with a formula of FeP.< [1] Its physical appearance is grey needles. Manufacturing of iron phosphide takes place at elevated temperatures, where the elements combine directly. [1] Iron phosphide reacts with moisture and acids producing phosphine (PH 3), a toxic and pyrophoric gas.
A phosphate coating is usually obtained by applying to the steel part a dilute solution of phosphoric acid, possibly with soluble iron, zinc, and/or manganese salts. The solution may be applied by sponging, spraying, or immersion. [6] Phosphate conversion coatings can also be used on aluminium, zinc, cadmium, silver and tin. [7] [8]
Organophosphorus chemistry is the scientific study of the synthesis and properties of organophosphorus compounds, which are organic compounds containing phosphorus. [1] They are used primarily in pest control as an alternative to chlorinated hydrocarbons that persist in the environment.
