摘要
以氯化镁和氨水为原料制得碱式氯化镁前驱物,通过控制反应条件以化学沉淀法与水热法结合制备纤维状Mg(OH)2,在最适宜的反应条件下得长度约为150μm,长径比大于30的纤维状氢氧化镁。
Magnesium chloride and ammonia liquor were used as starting materials to synthesis the precursor, basic magnesium chloride. Then fibrous magnesium hydroxide, having a needle -like crystal structure and having an aspect ratio of at least about 30 and an average length of about 150μm, was prepared by chemical precipitation method and subsequent hydrothermal synthesis method.
