2012年8月10日 · The pressure-temperature (P-T) phase diagram of ammonium nitrate (AN) [NH 4 NO 3] has been determined using synchrotron x-ray diffraction (XRD) and Raman spectroscopy measurements. Phase boundaries were established by characterizing phase transitions to the high temperature polymorphs during multiple P-T measurements using both XRD and Raman ...

2013年12月6日 · The phase diagram of ammonium nitrate in a log P–linear T plot, showing the phase transitions observed in pure AN (in black symbols) to- gether with those in ANFO (in blue) and Ammonal (in red).

Ammonium nitrate (NH4NO3) is produced by neutralizing nitric acid (HNO3) with ammonia (NH3). ... The manufacture of ammonium nitrate involves several major unit operations including solution formation and concentration; solids formation, finishing, screening, and coating; and product bagging and/or bulk shipping.

2023年5月15日 · In this article we will learn about all the methods for preparation of ammonium nitrate, structure of ammonium nitrate and all the applications of ammonium nitrate.

2012年8月14日 · The pressure-temperature (P-T) phase diagram of ammonium nitrate (AN) [NH(4)NO(3)] has been determined using synchrotron x-ray diffraction (XRD) and Raman spectroscopy measurements.

2013年12月6日 · To remedy the situation, we have carried out an extensive study to investigate the phase stability of AN and its mixtures with hexane (ANFO–AN mixed with fuel oil) and Aluminum (Ammonal) at high pressures and temperatures, using diamond anvil cells (DAC) and micro-Raman spectroscopy.

Ammonium nitrate is an ionic salt made up of the ammonium cation (NH 4) + and the nitrate anion (NO 3) –. The chemical formula of this compound is NH 4 NO 3 . Since Ammonium Nitrate contains half of the nitrogen (N) in the nitrate form and half in the ammonium form, ammonium nitrate is a widely used fertiliser.

2014年5月7日 · The present results confirm the recently proposed phase IV-to-IV' transition above 17 GPa 2 and provide new constraints for the melting and phase diagram of AN to 40 GPa and 400 °C.
