This paper discusses the results of the research carried out to study the structure, optical properties and thermophysical properties of a sample (nanopowder with a true density of 4.96 g/cm3, a particle size of 60 nm and a purity of 98.5%, SkySpring Nanomaterials, USA) with high purity. Based on the results of X-ray diffraction, the crystalline phase of MnFe2O4 ferrite nanoparticles was completely obtained and the values of the lattice parameters were determined. The results of the MID-IR analysis showed that the absorption coefficient (α) reaches its maximum value at 748 cm1 wave number. The optical properties of the as-prepared nanostructures were also investigated by VERTEX 70 V diffuse reflectance spectroscopy (DRS). As can be seen from the results of the DSC analysis, the effects occurring in the temperature range up to 300C clearly reflect the nature of the phase transitions and the amount of energy generated in the ferrite samples.

锰铁氧体纳米粒子的热物理和结构特性

本文讨论了为研究样品(真密度为 4.96 g/cm 3,粒径为 60 nm,纯度为 98.5% 的纳米粉末,SkySpring纳米材料,美国)具有高纯度。根据X射线衍射结果,完全得到了MnFe 2 O 4铁氧体纳米粒子的晶相,并确定了晶格参数值。中红外分析结果表明,吸收系数(α)在 748 厘米处达到最大值-1波数。还通过 VERTEX 70 V 漫反射光谱 (DRS) 研究了所制备的纳米结构的光学性质。从 DSC 分析的结果可以看出,在高达300C 清楚地反映了相变的性质和铁氧体样品中产生的能量。
