The paper discusses the features of polymer-nitrate synthesis of fine MgFeInO4 particles and presents experimental study results of the physico-mechanical properties of ceramics produced on their basis. According to powder XRD data, a single-phase ferrite-spinel powder can be obtained only as a result of hightemperature treatment of an X-ray amorphous precursor prepared by thermal decomposition of a mixture of polyvinyl alcohol and metal nitrates. Ceramics produced using submicron MgFeInO4 particles have a density close to the theoretical one. The results of microhardness measurements using the Vickers method showed that the resulting material has high hardness. The band gap energy of MgFeInO4 was determined from the DRS data. Based on the crystallographic and electrophysical characteristics of the synthesized material, its resistance to radiation-induced structural changes was predicted.

В статье обсуждаются особенности полимер-нитратного синтеза высокодисперсных частиц магний-индиевого феррита (MgFeInO4), и приводятся результаты экспериментального исследования физико-механических свойств керамики, изготовленной на их основе. По данным порошковой рентгеновской дифракции установлено, что однофазный порошок феррит-шпинели может быть получен только путем высокотемпературной обработки рентгеноаморфного прекурсора, образовавшегося в результате термического разложения смеси поливинилового спирта и нитратов металлов. Керамика, изготовленная с использованием субмикронных частиц MgFeInO4, имеет плотность, близкую к теоретической. Из результатов измерения микротвердости по методу Виккерса установлено, что полученный материал обладает высокой твердостью. По данным спектроскопии диффузного отражения определено значение энергии ширины запрещенной зоны MgFeInO4. С использованием кристаллографических и электрофизических характеристик синтезированного материала спрогнозирована его устойчивость к радиационно-индуцированным структурным изменениям.
