نترات الأمونيوم
The factory was created as a result of the Shell Crisis of 1915. At the beginning of World War I shells were filled with Lyddite, but this needed imported raw materials, and so trinitrotoluene (TNT) was adopted. TNT was expensive to make and was in short supply, so Amatol, a mixture of various proportions of TNT and Ammonium nitrate, was adopted instead.
