Abstract
The rate of hydration of magnesium oxide depends on the temperature an d rime of it spring. To describe the kinetics of hydration over the en tire temperature range measured, use can be made of the equation ln (I /(I - alpha) = (kt)(n), which was proposed for similar heterogeneous s ystems by Yerofeyev. The temperature dependence of rate constants conf orms to the Arrhenius equation. The activation energy also depends on temperature and the time of firing of MgO, and its values range from 5 0 to 93 kJ mol(-1).
