Aluminum Phosphide

Aluminum phosphide, is a binary salt, one of the NCHP acronyms (see Chapter 2). These salts have the specific hazard of giving off poisonous and pyrophoric phosphine gas when in contact with moist air, water, or steam. They will also ignite spontaneously upon contact with air. This compound is composed of gray or dark yellow crystals and is a dangerous fire risk. Aluminum phosphide decomposes upon contact with water and has a specific gravity of 2.85, which is heavier than water.

Chemical Properties

Product Usage

Aluminum phosphide is a highly effective inorganic phosphide primarily utilized as a broad-spectrum fumigant for pest control. Its primary application is in the protection of stored grains, such as wheat, rice, and corn, where it releases phosphine gas upon contact with atmospheric moisture to eliminate insects and rodents. In the logistics and tobacco industries, it is widely used for the fumigation of warehouses, shipping containers, and raw tobacco to prevent infestations. Additionally, it is employed in agriculture as a potent rodenticide for controlling burrowing pests in fields and orchards. Due to its high toxicity, it is valued for leaving no harmful residues on treated food commodities when used according to professional protocols.
