Аннотация

The influence of mechanochemical treatment on the lattice distortion of phosphorite was investigated by XRD, FTIR and 27Al MAS NMR. Increase in lattice distortion caused increase in citric solubility of phosphorite almost 3 times and achieving 53 % of total P2O5 contents. For the mechanochemical preparation of phosphorous fertilizer the presence of some quartz in phosphorite is prerequisite due to higher hardness of quartz than fluorapatite and consequently easier distortion of fluorapatites structure.
