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 introduction 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 reduce density in a particulate
ammonium nitrate product.
