Uses and applications

What the substance is used for, by industry and function

Rodenticides.

Hierarchical tree-shaped nanostructures, nanobelts, and nanowires of Zn3P2 were synthesized in a thermal assisted laser ablation process.

Use in thin-film cells.

Pharmacological actions

  • Rodenticides

How it is made

Direct combination of the elements at elevated temperature. White, red, or gaseous phosphorus can be used. Some phosphides can be prepared by reaction of phosphine with metals or their salts. Metallic phosphides can also be prepared by the electrothermal reduction of metal oxides in the presence of carbon and phosphates. (Phosphides)

By passing phosphine into a solution of zinc sulfate.
