Abstract
Mixtures of calcium and magnesium hydroxides and calcium dihydrogenphosphate in various molar ratios were ground in water with a fine grinding machine, which features multiring grinding media. Mechanochemical amorphization of the mixtures occurs quickly by grinding. The mixtures, after grinding for 5, 20, and 60 min, were then subjected to hydrothermal treatment at 573 K for 24 h. The influence of Mg/(Mg + Ca) molar ratio on the thermal behavior of the mechanically activated powders and the structure of the final products has been investigated. The microhomogeneity of Mg, Ca, and P elements on the samples is enhanced by the mechanochemical treatment. A shift in the X-ray diffraction peaks was observed among the final products with different grinding times, presumably due to a partial substitution of calcium by magnesium.
