Conclusions

  1. 1.

    The kinetics of the dehydration of the hydroxides Mg(OH)2, Be(OH)2, and Ca(OH)2 was studied by an electron diffraction method.

  2. 2.

    The data obtained did not confirm the mechanism of dehydration of Mg(OH)2 through an intermediate crystalline phase of the type of NiAs, which has been reported by certain authors.

  3. 3.

    The dehydration of Mg(OH)2 occurs by a continuous explosive conversion of Mg(OH)2 to crystals of MgO of the final dimensions. Growth of MgO crystals does not limit the rate of the process.

  4. 4.

    The dehydration of Ca(OH)2 and Be(OH)2 proceeds through two phases separated in time — formation and growth of nuclei.
