Structural Transformations Accompanying Mechanochemical Activation Of Natural Phosphorite From Syria

The effect of mechanochemical activation (MCA) on the structure and properties of Syrian phosphorite is investigated. The character of structural changes and their effect on the solubility of activated Syrian phosphorite are studied with the help of X-ray phase analysis, infrared and electron spectroscopy, and thermal analysis. It is established that MCA causes substantial structural perturbations in the initial phosphorite; they result in an increase in the reactivity and solubility of mechanochemically activated phosphorite samples.
