STUDY REGARDING THE HIGH-QUALITY AMMONIUM

The paper presents the studies performed regarding the process of ammo nium nitrate preparation with zinc- or manganese microelements, by int roducing in the melt, before granulation, the indigenous natural zeoli te, having zinc - or manganese - content. The zeolite inclusion in the ammonium nitrate does not modify the chemical and phase composition o f the ammonium nitrate, improves the thermal stability, as well as the quality of the fertilizer thus obtained.
