高纯氧化镁制备方法的优劣势2023-07-26 11:06·河北镁熙生物有限公司河北镁熙生物有限公司表示,高纯氧化镁是一种氧化镁的质量分数高于98%的氧化镁,用途极其广泛,如在橡塑高聚物领域,主要用作活化剂、硫化剂、稳定剂等,在陶瓷制品制造中,高纯氧化镁可用于特种瓷器坩埚、电绝缘制品和电容器等,由于其在光学、电学机械性能和化学性能方面极其优异,所以在光学透明材料、耐高温器件、激光材料等方面都具有应用潜力。高纯氧化镁的制备方法主要有:镁矿碳化法、卤水氨法、碳铵法、卤水热解法等,但是各种工艺有其自身的优缺点。镁矿碳化法由于受原料中含有的钙等杂质的影响,产物纯度很难提高,同时生产过程具有能耗高、生产成本高的特点,再卤水氨法由于在生产过程中易形成胶体,煅烧工艺比较难控制,造成局部烧结、活性低、回收率低和环保问题较突出等,因此工艺化意义也不大。目前生产高纯氧化镁主要有三大来源:镁矿石(菱镁矿和白云石等),卤水,海水。我国菱镁矿资源极其丰富,已探明工业储量为30亿吨,占世界总储量的1/3。由菱镁矿生产氧化镁工艺简单、投资少,生产成本低,产物质量高,废排放量小,较经济,因此具有很强的竞争力。该法已被业内人士重视,菱镁矿主要用于制备镁质耐火原料和制品、提炼金属镁及做防热、保温、隔音建筑材料等,在未来有着较大的发展空间。由菱镁矿生产氧化镁的主要工艺有:碳化法、酸溶法和铵浸法。碳化法工艺简单,不具腐蚀,产物质量稳定,设备简单,但是浸出率低,矿石利用率低,能耗大,所以目前无法应用到工业生产。酸溶法浸出率高,可是该方法需用大量浓硫酸,腐蚀性强,试剂消耗大,回收率低,成本高,故此法也未能适用到工业生产中。铵浸法获得产物纯度高,但工艺困难,腐蚀性强,沉淀时使用大量碳酸氢铵,接近1吨加6吨碳酸氢铵,原料消耗大,回收率低,得到硫酸铵未实现循环使用,成本高而应用不广。要想晚年好,养儿能防老,子女的孝顺不可或缺。
