yellow or grey crystals Aluminum phosphide is a pyrophoric, dark gray or dark yellow crystalline solid

Aluminum phosphide Basic Attributes

Molecular Weight：

57.96

Exact Mass：

61.98660

EC Number：

244-088-0

HScode：

2848000010

Characteristics

PSA：

XLogP3：

0.55080

Appearance：

Aluminum phosphide is a dark gray or dry, yellow, crystalline solid. It reacts with moisture to give phosphine, a flammable and poisonous gas. Normally, phosphine will spontaneously ignite upon contact with air. If there is an excess of water, the phosphine fire will not normally ignite any surrounding combustible material.

Density：

2.85 g/cm³ @ Temp: 15 °C

Melting Point：

2550 °C

Water Solubility：

Solubility in water: reaction

Storage Conditions：

Extremely reactive with air, moisture and compounds containing active hydrogen and therefore must be kept under a blanket of inert gas. /Aluminum alkyls/

Vapor Pressure：

Very low, even at 1000 deg C

Toxicity：

Oral-human TDL0: 21 mg/kg; Oral-rat TDL0: 10 mg/kg

Flammability characteristics：

Inflammable in water; flammable and highly toxic phosphine gas in the air and in acid and water

Odor：

Garlic odor

Aluminum phosphide Use and Manufacturing

Methods of Manufacturing

In the synthesis method, the red phosphorus and the aluminum powder are evenly mixed according to the ratio of ingredients and then ignited and burned. The reaction produces aluminum phosphide. After the reaction product is crushed, a slow-release agent ammonium carbamate and a binder are added. After mixing, the tablet is prepared to obtain aluminum phosphide. Finished product. Its Pa+4Al→4AlP

Uses

Source of phosphine; in semiconductor research; as fumigant.
