  • Rapid Synthesis of Dittmarite by Microwave-Assisted ...

    www.hindawi.com/journals/amse/2012/968396 Dittmarite was obtained using MgO and (NH 4 ) 2 HPO 4 as raw materials via microwave-assisted hydrothermal method for 3 min at 120°C. The resulting samples were investigated by X-ray powder diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, and thermogravimetry-differential thermal analysis.

    pubs.acs.org/doi/abs/10.1021/acs.cgd.9b00094 This study provides the first data on the preparation of ammonium iron–manganese phosphates monohydrates, NH4Mn1–xFexPO4·H2O, with a dittmarite-type structure in the whole concentration range. The structure, Mn2+/Fe2+ distribution over 2a crystallographic site, and morphology of the mixed dittmarite salts are assessed by means of powder X-ray diffraction, infrared spectroscopy, electron ...
  • Hydration/dehydration characteristics of struvite and ...

    link.springer.com/article/10.1007/BF01130204 Dittmarite is thermally more stable than struvite and like struvite also forms magnesium hydrogen phosphate on decomposition. At room temperature and in the presence of excess water, dittmarite can slowly transform to the hexahydrate, struvite. The consequence of structural similarities between struvite and dittmarite and conditions under which ...

    www.sciencedirect.com/science/article/pii/S0045653520304380 Dittmarite, struvite, and sylvite represent the hydrothermal product precipitated at a temperature of 120 O C. The outcome of synthetic lab-made hydrothermal minerals could be considered quite accurate, since dittmarite, struvite and sylvite peaks have been judged by the Rietveld method close in agreement with the literature data ( Bayuseno and ...
