It’s used as a rodenticide.[5] Zn3P2 is a II-V semiconductor with a direct band hole of 1.5 eV[6] and should have purposes in photovoltaic cells.[7] A second compound exists within the zinc-phosphorus system, zinc diphosphide (ZnP2). Zinc phosphide (Zn3P2) is an inorganic chemical compound. It’s a gray stable, though industrial samples are sometimes darkish and even black.

Synthesis and reactions[edit]
Zinc phosphide reacts with water to provide phosphine (PH3) and zinc hydroxide (Zn(OH)2):
Construction[edit]
The crystalline construction of zinc phosphide is similar to that of cadmium arsenide (Cd3As2), zinc arsenide (Zn3As2) and cadmium phosphide (Cd3P2). These compounds of the Zn-Cd-P-As quaternary system exhibit full steady solid-solution.[12]
Functions[edit]
The New Zealand Environmental Safety Authority has authorized the import and manufacture of Microencapsulated Zinc Phosphide (MZP Paste) for the bottom management of possums. The appliance was made by Pest Tech Restricted, with assist from Connovation Ltd, Lincoln College and the Animal Well being Board. Will probably be used as a further vertebrate poison in sure conditions.
Security[edit]
The explanation for its toxicity is the discharge of phosphorus compounds, often phosphine, when it reacts with water and acids. Phosphine can be denser than air and should stay near the bottom with out ample air flow. Phosphine may be very poisonous and, with hint quantities of P2H4, pyrophoric.
