Arsenic Triphosphide

Arsenic triphosphide is a compound with the chemical formula AsP3. It consists of one arsenic atom and three phosphorus atoms, which are covalently bonded together in a tetrahedral structure.

The compound is a solid with a dark gray color and a metallic luster. It has a high melting point of 1,200°C and is insoluble in water but soluble in some organic solvents.

Arsenic triphosphide is used in the semiconductor industry as a source of phosphorus dopant for n-type doping of silicon and other semiconductors. It can be produced by reacting arsenic and phosphorus in a vacuum or in an inert atmosphere at high temperatures.

The compound is highly toxic and poses health hazards to humans and animals. It can enter the body through inhalation, ingestion, or skin contact and can cause acute and chronic poisoning. Therefore, proper precautions must be taken when handling and disposing of arsenic triphosphide.
