Explosion parameters have been measured for ferromanganese, ferrosilicon and ferrotitanium powders in a 1m ³ chamber. Maximum pressures of 2.8 3.9 bar, at maximum rates of rise of 8.9 21.8 bar/s were determined. Individual entries are:

• Ferromanganese, 4383

• Ferrosilicon, 4384

• Ferrotitanium, 4385

Self-sustaining thermal decomposition of NPK fertilisers is apparently possible if crystalline potassium nitrate is present from a exchange reaction of ammonium nitrate [1]. Almost pure fertiliser grades of ammonium nitrate are legally restricted in some countries because of its instability [2]. An investigation of the (large) proportions of other fertiliser components needed to make ammonium nitrate undetonable has been made [5]. An extensive review of safety aspects of ammonium nitrate based compound fertilisers has been published [3]. So has a study of their thermal decomposition and the implications for storage [4].
