What is a Zinc phosphide (Zn₃P₂)?

Zinc phosphide (Zn₃P₂) is an inorganic compound consisting of zinc and phosphorus. It is typically found as a gray or black crystalline solid and is known for its high toxicity. Because of its poisonous nature, zinc phosphide is mainly used as a rodenticide, effectively controlling pests like rats and other small mammals. The compound is highly toxic to animals, including humans, if ingested.

When animals consume zinc phosphide, it reacts within their digestive system, producing zinc salts that are toxic to the animal. This leads to poisoning and, in many cases, death. The compound works by disrupting normal metabolic functions and causing severe damage to internal organs. As a result, it is critical to handle zinc phosphide with extreme caution, especially in agricultural and food processing environments.

In addition to its use as a rodenticide, zinc phosphide has some applications in electronic and specialized industries, although its toxicity limits its broader usage. It is not commonly used in household settings, and its use should always be controlled and monitored.
