Abstract

Al-doped Co-Cd ferrites Co_0.4Cd_0.6 Al_xFe_2–xO₄ (x = 0.1, 0.2, 0.3, 0.4) were prepared by solution-combustion synthesis (SCS) and characterized by XRD, SEM, EDAX, and FTIR. A simple cubic spinel structure of synthesized ferrites with a = 8.496–8.545 Å was confirmed by XRD. The uniform size distribution of ferrite grains was observed in SEM micrographs. The elemental analysis confirmed the presence of all metal ions from the ferrite formula. FTIR spectra showed two absorption bands, υ₁ (568–580 cm^–1) and υ₂ (413–451cm^–1), attributed to Me–O vibration modes at tetrahedral and octahedral sites, respectively. Our results may turn interesting to those engaged in combustion synthesis of ferrites.

溶液燃烧合成Al掺杂Co-Cd纳米铁氧体的制备与结构表征

摘要

通过溶液燃烧合成（SCS）制备掺铝的Co-Cd铁氧体Co _0.4 Cd _0.6 Al _x Fe _{2- x} O ₄（x = 0.1、0.2、0.3、0.4），并通过XRD，SEM，EDAX和FTIR。XRD证实了a = 8.496–8.545Å的合成铁氧体的简单立方尖晶石结构。在SEM显微图中观察到铁素体晶粒的均匀尺寸分布。元素分析证实了铁素体分子式中所有金属离子的存在。FTIR光谱显示两个吸收带，υ ₁（568-580厘米^-1）和υ ₂（413-451cm ^-1），分别归因于四面体和八面体位置的Me–O振动模式。我们的结果可能对那些从事铁氧体燃烧合成的人变得有趣。
