A METHOD OF PREPARATION OF AMMONIUM NITRATE (AN) PRODUCTS HAVING IMPROVED THERMAL STABILITY AND PRODUCT COMPOSITES HAVING IMPROVED THERMAL STABILITY

摘要

The present invention relates to preparation of ammonium nitrate (AN) products having improved thermal stability, products thereof and their use in explosives or fertilizers. A solid drying agent is mechanically mixed with AN-particles and said agent has water binding capacity, is compatible with the end use of the AN product and has a critical relative water vapour pressure above the agent being less than said pressure above the AN product. Preferred drying agent will be AN-particles comprising magnesium nitrate. The drying agent may have a water binding capacity being equal to or larger than the content of free water in the AN-particles.
