Ferro Phosphorus

(FeP) Atomic Numbers 26,15

Ferro Phosphorus exists in many allotropic forms. Phosphorus (white) is used by the military for smoke generation as well as being used in commercial rodent poison. Red Phosphorus, which is comparatively harmless, is used in matchsticks. When combined with Lithium Iron, this material is used in the production of rechargeable batteries. Ferro Phosphorus, a combination of phosphorus with iron, is used as an ingredient in high-strength low-alloy steel and is used as a good dehydrating agent that can remove water during the alloy formation.

Properties of Ferro Phosphorus

Ferro Phosphorus, as an additive to the production process of ferrous metals, will impart several desirable properties upon the resulting alloy. One of the primary benefits of adding Ferro Phosphorus is that it will act as a drying agent which will remove water content from any nitric acid used during manufacturing. Additionally, adding Ferro Phosphorus to an alloy prevents oxidation and the later rusting of metals.

Production of Ferro Phosphorus

Ferro Phosphorus is a by-product of the steel manufacturing process, as when pig iron is being converted, the conversion process will skim Ferro Phosphorus from the top of the slag. This was first done using the basic Bessemer process or the Thomas process.

Uses of Ferro Phosphorus

By keeping varied amounts of Ferro Phosphorus in the process, the metal can be made more brittle if desired. For example, the use of phosphorus as an alloying element in powder metallurgy has been around since 1939. Sintered steel alloy with Ferro Phosphorus has improved strength, as compared to unalloyed sintered steel. Recent developments in Ferro Phosphorus powder has allowed sintered steels to have high strengths in combination with good ductility. Ferro Phosphorus is also used as a manufacturing drying agent.

Ferro Phosphorus Market

The Ferro Phosphorus market was a small market at the onset, and has neither increased nor decreased over the past several decades, with the one exception being when Australia joined the market place. The Ferro Phosphorus market is best examined in terms of the more widely known Phosphides market, where after a three-year downward trend in prices, the industry appears to be heading towards recovery this year. However, due to the increasing demand for commercial fertiliser, price increases are expected, but not in sales. Recent prices for Diammonium Phosphate, the most common phosphate fertiliser, are the key factor that is driving the market, and Ferro Phosphorus powders are expected to have little impact on the market place.
