摘要：
A mixed hydroxide hydrogel of the MgO-ZrO2 system has been synthesized by wet interaction in the aqueous phase. Both the mole ratio of MgO : ZrO2, and the preparatory conditions strongly influence the particle morphology. This was also reflected in the dehydration-rehydration characteristics studied under equilibrium conditions. Both dehydration and rehydration followed a discontinuous path thereby indicating heterogeneity in the bonding of water to the gel structure.
