| 摘 要： | 本文采用IR、XRD、TG、DTA等测试手段对MgO重新水合及其两类羟基进行了研究。发现:MgO水解在实验条件下仅发生在表面浅层;水合得到自由、水合两类羟基;600℃灼烧使两类羟基脱除;自由羟基由水合羟基在碱作用下生成;适量添加Li~+于真空,实验温度的条件下能使自由羟基消失生成Li~+OH~-,进而发生2Li~+OH~-→Li_2O+H_2O,

| Abstract: | In this paper, renew hydration of MgO and two type hydroxyl group are investigated by the technology of IR、XRD、 TG and DTA. We find that hydrolysis of MgO, at experiment condition, carry only on the surface, two type hydroxyl group of hydration arc taken off at 600℃, and find that hydration hydroxyl group and O build up free hydroxyl group, suitable quantity Li+addcd, at Vasunm and 300℃, can react with free hydroxyl group to form Li+OH-and follow reaction: |
