【摘要】：通過(guò)水熱法在燒結(jié)的多孔鎂基板上制備了納米厚度的氫氧化鎂(Mg(OH)_2)疊片。分別用SEM及XRD表征了水熱合成過(guò)程中基板的形貌和物相變化。結(jié)果表明,將水熱合成的反應(yīng)時(shí)間控制在20~40 min之內(nèi),可以制備出具有100 nm左右厚度的、不同緊密程度的Mg(OH)_2疊片。水熱合成的反應(yīng)時(shí)間超過(guò)40 min,Mg(OH)_2疊片將會(huì)逐漸從基板表面生長(zhǎng)合并為塊狀晶體。同時(shí),對(duì)水熱反應(yīng)過(guò)程中氫氧化鎂晶體的形核和長(zhǎng)大機(jī)理進(jìn)行了探討。
[Abstract]:Nanocrystalline magnesium hydroxide (MgOHJ _ 2) laminated on sintered porous magnesium substrate was prepared by hydrothermal method. The morphology and phase change of substrate during hydrothermal synthesis were characterized by SEM and XRD, respectively. The results show that when the reaction time of hydrothermal synthesis is controlled within 20 ~ 40 min, MgO _ H _ H _ 2O _ 2 with thickness of about 100nm can be prepared. The reaction time of hydrothermal synthesis is more than 40 min MgO / OHH\ -2 stack will gradually grow from the substrate surface to form a bulk crystal. At the same time, the nucleation and growth mechanism of magnesium hydroxide crystals during hydrothermal reaction were discussed.
