Description

Ammoniwn nitrate,NH4N03, is a colorless crystalline solid existing in two forms, Between 16 and 32°C, the crystals are tetragonal; between 32 and 84 DC, the crystals are rhombic. The melting point of NH4N03 is 169.6 DC, and it decomposes above 210°C. When heated, ammonium nitrate yields nitrous oxide gas. Ammonium nitrate is soluble in water, in acetic acid solutions containing ammonia, is slightly soluble in ethanol, and is moderately soluble in methanol. Ammoniwn nitrate is a very insensitive

Appearance：

Ammonium nitrate is commercially available both as a colorless crystalline solid and processed into prills for specific applications. Soluble in water. Does not readily burn but will do so if contaminated with combustible material. Accelerates the burning of combustible material. Produces toxic oxides of nitrogen during combustion. Used to make fertilizers and explosives, and as a nutrient in producing antibiotics and yeast.

Density：

Flash Point：

210ºC

Water Solubility：

H2O: 190 g/100 mL (20 ºC)

Storage Conditions：

Store at RT.

Vapor Pressure：

2.3 kPa at 20 deg C in water solution; 1.5 kPa at 20 deg C in saturated NH4NOs solution

Toxicity：

LD50 orally in Rabbit: 2462 mg/kg

Explosive limit：

Explosions of stored ammonium nitrate are responsible for some of the worst chemical disasters on record. Several of these incidents, including two in Germany in 1921, occurred during attempts to break up large piles of solidified or caked ammonium nitrate and ammonium sulfate mixtures using explosives. In both cases, the initial blast intended to break up solid ammonium nitrate initiated an unintended general detonation of the ammonium nitrate or ammonium sulfate mixture.

Odor：

Odorless

Storage features：

Separated from combustible substances and reducing agents. Dry. Well closed.

Stability/Shelf Life：

Stability during transport: If heated strongly, decomposes, giving off toxic gases and gases which support combustion. Undergoes detonation if heated under confinement.
