METHOD OF REDUCING DENSITY BY MEANS OF GAS-GENERATING AGENT

摘要

This invention relates to a method of reducing density in an ammonium nitrate product. The method comprises providing a gas generating agent in the form of a water-insoluble solid compound capable of generating gas by chemical reaction, and providing an ammonium nitrate product. The water-insoluble solid gas generating agent is introduced into the ammonium nitrate product under conditions causing gas generation by the gas generating agent in the ammonium nitrate product. The ammonium nitrate product is particulated to form a particulated prilled ammonium nitrate product with reduced density. The invention also relates to a particulated ammonium nitrate product produced by this method and to the use of a gas generating agent in the form of a water-insoluble solid compound to reduce density in a particulated ammonium nitrate product.
