Lead Zinc Phosphate

Zinc phosphate - Wikipedia

Zinc phosphate is an inorganic compound with the formula Zn 3 (PO 4) 2)(H 2 O) 4.This white powder is widely used as a corrosion resistant coating on metal surfaces either as part of an electroplating process or applied as a primer pigment (see also red lead).It has largely displaced toxic materials based on lead or chromium, and by 2006 it had become the most commonly used corrosion inhibitor.

Adding Phosphate to Flint Water

• Adding phosphate to the water helps build and maintain scale by collecting on the sides of the pipes and sticking to the metal. Lead Pipe No scale. Water Lead Pipe Water Phosphates will build up the scale. Why are we putting phosphate in the water? • Lead pipes, solder, and faucets used to be common. We now know that lead can harm our health.

Manganese & Zinc Phosphate Coating | Metal Coatings

Zinc phosphate coatings (Type Z) are also available and are mainly used for rust proofing on ferrous metals. They can be applied by immersion or spraying. Zinc phosphate is a lighter alternative to manganese phosphate, while providing resistance to harsh elements that tend to wear products quickly.
