Thermochemical Properties and Decomposition Kinetics of Ammonium Magnesium Phosphate Monohydrate

“…The several strong and sharp absorption bands from 950 to 1200 cm -1 were due to stretching modes of group. 19 The most intensive band observed at 1070 cm -1 was ascribed as the symmetric stretching of 3 4 PO -. Another strong absorption observed at 984 cm -1 was attributed to the 3 4 PO -antisymmetric stretching mode.…”

Sonochemical Synthesis of Amorphous Zinc Phosphate Nanospheres

“…The broad bands shown at 400 ~ 700 cm ) were attributed to the bending and complex stretching vibrations of PO4 3-group, respectively. 24 In the reference FT-IR spectrum, the vibrational bands split into three distinct peaks: 954 cm -1 , 1021 cm -1 , 1107 cm -1 due to P-O bending, antisymmetric stretching of PO4 3-, and symmetric stretching of PO4 3-, respectively. 10 The significant differences between the reference FT-IR spectrum and the FT-IR spectrum of as-prepared nanospheres are the chemical shift of peaks, relative peak intensity, and the overlap between peaks in the vibrational bands.…”
