Abstract

Binary and ternary composite based on multicomponent oxides attract great attention due to scientific novelty and practical importance. The features of the interphase interactions can lead to synergetic effect with violation of the additivity principle that can be realized in practical applications. The main problem in this case is investigation of the correlation between chemical composition (phase composition and phase ratio), peculiarities of the preparation conditions and physical properties of such materials. Functional composites based on soft magnetic oxides (Ni₀_·₄Cu₀_·₂Zn₀_·₄Fe₂O₄ or NCZ and CoFe₂O₄ CF) were prepared. by sol-gel method. Two-component (NCZ/CF; NCZ:FP; CF:FP]) and tree-component ([NCZ/CF]:FP) composites were prepared using FEP polymer. It was observed anomalous behavior of the lattice parameters for ceramic samples and ceramic composite. This is explained by the surface crystallite compression effect at nanoscale. The composition, structure, microwave properties of the samples have been established by XRD, SEM and high frequency spectroscopy. The values of RL coefficient in the 5–10 GHz range open wide opportunities for the development of electromagnetic absorbers and antenna technologies.

基于尖晶石的功能二元和三元纳米复合材料：成分-结构-微波性能

基于多组分氧化物的二、三元复合材料因其科学新颖性和实用价值而备受关注。在实际应用中，相间相互作用的特点会导致违反可加性原理的协同效应。这种情况下的主要问题是研究化学组成（相组成和相比）、制备条件的特殊性和这种材料的物理性质之间的关系。制备了基于软磁氧化物（Ni0·4Cu0·2Zn0·4Fe2O4或NCZ和CoFe2O4 CF）的功能复合材料。溶胶-凝胶法。双组分(NCZ / CF;NCZ:《外交政策》;用FEP聚合物制备了CF:FP]和[NCZ/CF]:FP)复合材料。观察了陶瓷样品和陶瓷复合材料晶格参数的异常行为。这可以用纳米尺度下的表面晶体压缩效应来解释。通过XRD、SEM和高频光谱分析确定了样品的组成、结构和微波性能。5-10 GHz范围内RL系数的值为电磁吸收器和天线技术的发展提供了广阔的机会。
