ammonium nitrate coal dust

ANFO explosive Britannica

Other articles where ANFO is discussed: explosive: Ammonium nitrate–fuel oil mixtures: In 1955 it was discovered that mixtures of ammonium nitrate and fine coal dust would give very satisfactory blasting results in the large (about 22.5-centimetre, 9-inch) holes used in open-pit coal mines to remove the rock and soil covering the coal.

Ammonium nitrate NH4NO3 - PubChem

Ammonium nitrate changes its crystal form every time it passes through a temperature of 90 °F. It also absorbs moisture rapidly from the air when the humidity exceeds about 60%. The exact percent varies with the temperature. In dry atmospheres the material dries out. Both these processes cause the particles to knit together.

Aerosol pH Dynamics During Haze Periods in an Urban ...

2019-7-8  In the relationship between pH and ammonium/ammonia, periods that were dust-rich and mixed sulfate-nitrate-coal regions were identified according to the relative contributions of those factors (Figure 3). Table S1 shows the average source contribution (%), concentrations (μg/m 3) of NH 3 (g) and TWI, and pH in dust-rich and mixed regions.

2005-12-1  Ammonium is practically not incorporated into in MD. It is bound to the fraction of soil dust containing organic matter. The yields of nitrate and sulfate formation increase with the alkalinity, or the [Ca]/[Si] ratio in MD. Ca-rich soil dust is able to incorporate much larger amounts of sulfate and nitrate than coal fly ash.

Ammonium Nitrate – Nap Group

– Ammonium nitrate is also used in instant cold packs. In this use, ammonium nitrate is mixed with water in an endothermic reaction, which absorbs 26.2 kilojoules of heat per mole of reactant. – Products of Ammonium nitrate reactions are used in Airbags. Sodium azide (NaN3) is the chemical used in airbags, as it decomposes to Na (s) and N2 (g).

Ammonium nitrate storage and handling

Segregate ammonium nitrate from all other incompatible goods by 3 m or more. Do not store ammonium nitrate fertilisers of Class 9 (UN 2071) with ammonium nitrate of class 5.1. If one of the goods present is a liquid or if the goods may react violently with the ammonium nitrate, store them in separate compounds or at least 5 m or more apart.
