研究了无水硫酸镁和氯化镁在不同的熔融硝酸盐和亚硝酸盐中的反应，得到了细小的氧化镁粉末。建立了反应的化学计量比，研究了各种反应条件对合成的氧化镁粉末性能的影响。在硝酸盐熔体中加入Lux-Flood碱，可以降低反应温度，进一步降低氧化镁粉末的微晶尺寸。结果表明，在600℃以下，从熔融的硝酸盐和亚硝酸盐中可以析出非常细小的高纯度的氧化镁粉末，如果对沉淀的粉末进行适当的处理，可以得到软团聚的氧化镁粉末。
The reactions of anhydrous MgSO4 and MgCl2 in different molten nitrates and nitrites which produce fine MgO powders were studied. The stoichiometries of the reactions were established and the effects of various reaction conditions on the properties of the MgO powders produced were investigated. The addition of Lux-Flood bases to nitrate melts can lower the reaction temperatures and further lower the crystallite size of the MgO powders produced. The results showed that very fine MgO powders with high purity can be precipitated from molten nitrates and nitrites at temperatures below 600°C, and these powders can be obtained with soft agglomeration if the powders precipitated are properly processed.
