Phosphate minerals

Jump to navigation Jump to search

Phosphate minerals are those minerals that contain the tetrahedrally coordinated phosphate (PO43-) anion along with the freely substituting arsenate (AsO43-) and vanadate (VO43-). Chlorine (Cl-), fluorine (F-), and hydroxide (OH-) anions also fit into the crystal structure.

The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common.

Examples include:

Applications

Phosphate minerals are often used for control of rust and prevention of corrosion on ferrous materials, applied with electrochemical conversion coatings.
