Different solution pHs induce protonation or deprotonation of the oxyacid ligand, thus modifying its symmetry (Guan et al.
These results indicated that a lot of instantaneous energy during the mechanical impact resulted in the rapid increase of temperature of the local surface of the specimen, which led to the phosphorus-containing groups on the surface of the specimen thermally decomposed to form the phosphoric oxyacid. It covered over the surface of the specimen to prevent the reaction of the specimen with liquid oxygen which was in accordance with the mechanism that organophosphorus compounds could work in the condensed phase to inhibit the combustion [26],
