Abstract: In this paper, renew hydration of MgOand two types of hydroxyl groups were investigated by the techniques of IR, XRD, TG-DTA, It is found that the hydrolysis of MGO, under the experiment conditions, occured on the surface, the two types of hydroxyl groups of hydration are taken off at 600℃, the hydration hydroxyl group and O- build up free hydroxyl group, the two types of hydroxyl groups of MgOare influenced by Li+ added.

Key words: Hydration of MgO, Hydroxyl group, Adding Li
