Nanocrystalline LiZnMn-ferrite powders were synthesized by solution combustion at various glycine-nitrate ratios (G/N = 0.2, 0.4, ..., 1.4). Elemental analysis showed that the composition of the obtained samples corresponds to the ferrite-spinel Li0.45Zn0.05Mn0.06Fe2.43O4. Scanning electron microscopy showed that the compositions possess a porous microstructure and a developed surface; x-ray phase analysis attests that the synthesized LiZnMnFe-spinel is single-phase and possesses a high degree of crystallinity (to 99%). It was shown that the magnetic and dielectric characteristics of the obtained samples systematically change depending on the redox ratio of the reaction mixture and reach maximum values at stoichiometric value G/N = 0.4 – 0.6.

陶瓷前纳米结构的Liznmn铁氧体粉末:合成,结构和电磁性能

纳米晶LiZnMn-铁氧体粉末是通过溶液燃烧以各种甘氨酸-硝酸盐比率(G / N = 0.2、0.4 ,...,1.4)合成的。元素分析表明,所得样品的组成与铁素体-尖晶石Li 0.45 Zn 0.05 Mn 0.06 Fe 2.43 O 4对应。扫描电子显微镜显示该组合物具有多孔的微观结构和发达的表面。X射线相分析证明合成的LiZnMnFe-尖晶石是单相的,并且具有很高的结晶度(至99%)。结果表明,所获得样品的磁和介电特性根据反应混合物的氧化还原比而系统地变化,并在化学计量比G / N = 0.4 – 0.6时达到最大值。
