ammonia dynamite

Ammonia dynamite is a type of dynamite that uses ammonium nitrate as a primary ingredient, often replacing some or all of the nitroglycerin found in traditional dynamite. This substitution makes the explosive safer and less expensive.12

Dynamite itself was patented in 1867 by Alfred Nobel. It is based on nitroglycerin but is made safer by mixing it with absorbent materials like kieselguhr (a porous earth) or wood pulp. Later developments included gelatinous dynamites and "extra dynamites" which incorporated ammonium nitrate for improved safety and cost-effectiveness. Ammonia dynamites, particularly low-density versions, were developed to provide a cost-saving alternative by diluting the explosive mixture with ingredients like bagasse.12
