Method of preparation of ammonium nitrate products having improved thermal stability and products thereof. |
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. |
