The kinetics and thermodynamics of formation of chloromagnesium cements, which involves magnesium oxide, the main component of metallurgical sludge produced in manufacture of magnesium, were studied. The rate constants, activation energy, frequency factor, and thermodynamic constants of the reactions in which crystalline hydrates of composition 3Mg(OH) 2·. MgCl 2·8H 2O and 5Mg(OH) 2·MgCl 2·2H 2O are formed were calculated.The study was financially supported by the R&D Program Research by Higher School in Priority Areas of Science and Technology of the Ministry of Education of the Russian Federation and by an individual grant for support of research by postgraduate students at higher school institutions of the Ministry of Education of the Russian Federation (A03-3.21-451)
