摘要：

The nature of the lattice disorder generated by prereactional phenomena in Ca(OH)//2 is investigated by single-crystal neutron diffraction. A contraction of the layers is observed and the resulting distortions along the c axis increase; above a critical concentration of defects, the distortions along the c axis can no longer increase and a disorientation of the layers occurs to accomodate the newly created defects. This disorientation causes the relaxation of the distortions. The characteristic temperatures at which the above mentioned phenomena occur are strongly dependent on the water pressure and take place far below the temperature of onset dehydration.
