摘要
以唐山南堡盐场的卤水为原料,以碳酸氢铵为沉淀剂,制备了活性氧化镁。研究了沉淀反应条件如反应物浓度、反应温度、反应时间、陈化时间和煅烧温度等对产品性能的影响,并通过实验研究确定了制备活性氧化镁的最佳工艺条件:碳酸氢铵与氯化镁的物质的量比在2.0∶1.0～2.3∶1.0;反应物浓度在0.8～1.4 mol/L;反应温度在40～55℃;反应时间在45～75 min;煅烧温度在600～750℃。
Using bittern from Tangshan Nanpo saltern as raw material and ammonium bicarbonate as precipitant, the active magnesium oxide was prepared. Effects of raw material concentration and proportion, reaction temperature and time on precipitation reaction were studied. , the optimum processing conditions and the key factors in preparation of high active and purity magnesium oxide were achieved.
