Wetprocess phosphoric acid (H 3 PO 4) is produced by the decomposition of phosphate raw material (apatite concentrate) with sulfuric acid and by the filtration of prepared pulp. Wetprocess phosphoric acid is the main raw material in the production of phosphoric and compound fertilizers, feed phosphates.

pure Phosphoric Acid poses less severe corrosion problems than those seen on plants using the wet process. This discussion will concentrate on the sealing of plants using the wet process. Phosphoric Acid in its pure form, without contaminants, is less corrosive to many metals and alloys than, for example, Sulfuric or Hydrochloric acid.

Phosphoric acid is made by two processes: a) the 'wet' process. b) thermal process. The thermal method normally produces a more concentrated and purer product, but is energy intensive (because of the manufacture of phosphorus itself. Acid produced by the 'wet' route is less pure but is used in the manufacture of fertilizers.
