Sažetak
High purity magnesium hydroxide has been synthesized from seawater with the addition of dolomite lime as reagent. High intensity of ultrasound assisted crystallization of magnesium hydroxide was carried out during the precipitation in intention to obtain fine particles of Mg(OH)2 as well as to prevent agglomeration of them. The investigations were conducted on magnesium hydroxide samples in the form of sludge and voluminous powder. The composition, morphology and properties of the product were determined by chemical, XRD, FTIR and SEM/EDS analysis. The particle size distribution was detected by the laser light scattering method. The results have shown that the mean particle size of magnesium hydroxide sludge is 5.75 µm, while voluminous powder is 7.58 µm. The morphology of magnesium hydroxide voluminous powder is in the form of aggregated filamentous (up to 300 nm in size) or flake structures.
