Ferrous Metals; Its Types, Uses, Properties [Complete Guide]

Ferrous Metals List Their Types and Properties 1. Pig Iron Pig Iron is the first or basic form in which Iron is prepared as the metal from its ores. It is, therefore, impure and crude and requires subsequent processing to develop Cast, Wrought Iron, and Steel, which are the common Ferrous Metals used in construction and industries.

Sulfate Industrial Chemicals Manufacturers,Industrial

Iron(III) sulfate, is a compound of Iron and sulfate (made of sulfur and oxygen atoms).The compound is different from the more common Iron(II) sulfate in that the ratio of sulfate ions to iron ions is larger. Ferric sulfate is produced on a large scale by reacting sulfuric acid with a hot solution of ferrous sulfate, using an oxidizing agent (such as nitric acid or hydrogen peroxide).
