【摘要】以工业级Mg（OH）₂为原料,应用水热技术对Mg（OH）₂晶体形貌和颗粒尺寸进行改性。考察了水、乙醇和尿素3种水热溶剂对Mg（OH）₂晶体的影响。通过扫描电镜（SEM）表征可知,3种水热溶剂在一定程度上都可以改善工业级薄片状Mg（OH）₂晶体的形貌和团聚状态。尤其是尿素对Mg（OH）₂改性效果最为明显,在250℃下改性可以得到尺寸在10μm,形貌非常规整的立方体晶体。更多还原

【Abstract】 A method of hydrothermal modification on industrial grade Mg（OH）₂ particles in ethanol, water and urea solution was investigated. Influence of morphology and size of hydrothermal products was studied. According to SEM, morphology and aggregation of Mg（OH）₂ crystals were improved greatly. Effects of urea solution was obvious, size was increased up to 10μm and morphology of Mg（OH）₂ was cube crystal at the temperature of 250℃.更多还原
