High-purity magnesia was obtained by commercial magnesium sulfate and charcoal powder...; magnesium sulfate; charcoal powder; high-purity magnesium oxide; calcination 我国高纯氧化镁(w(MgO)≥98%)产品供不应求,亟需开发研究[1].制备高纯氧化镁的常用方法有卤水纯碱法,卤水碳铵法,白云石碳化法,菱镁矿碳化法等[2-6].卤水纯碱法受到区域的限制,只适用于卤水,纯碱资源较丰富的地区;卤水碳铵法生产成本高,并......
are high-purity copper nanoparticles with the fcc structure taking a mixture of fishbone-like and irregular shapes. When the concentration of Cu2+ increases from 0.03 to 0.09 mol/L, the average size... closely to the JCPDS file No. 04-836 (d=2.088, 1.808 and 1.278 nm). This clearly indicates that the as-prepared powders are high-purity copper with fcc structure, and oxide copper and other impurities......
