В статье исследуются основные физико-химические свойства магнитных глин. Структурные изменения в суспензиях магнитно-глинистых композиционных материалов оценивали путем измерения электрической проницаемости путем прямого измерения емкости датчика и путем компьютерного измерения частоты электрического сигнала, обратно пропорциональной емкости датчика. В исследовании использовалась природная бентонитовая глина Таганского месторождения (Восточно-Казахстанская область). Магнетит синтезирован методом соосаждения солей железа с магнитными-глинистыми композитами. Были исследованы различные составы глинисто-магнетитовых соединений для изучения магнитных свойств образцов. Согласно исследованию, с увеличением содержания магнетита в составе магнитные свойства увеличиваются. Однако увеличение количества магнетита в составе приводит к потере устойчивости суспензии. Стабильность суспензии также исследовали путем измерения размера частиц. В зависимости от результатов исследования 20% магнетит-глинистый состав был оптимальным значением для магнитного раствора.

This article studies the main physical and chemical properties of magnetic clays. Structural changes in magnetic clay composite suspensions were evaluated by measuring the permittivity through direct measurement of the sensor capacitance and through computer measurement of the frequency of the electric signal inversely proportional to the sensor capacitance. Natural bentonite clay of the Tagan field (East Kazakhstan region) was used in this study. Magnetite synthesized by the method of co-precipitation of iron salts with magnetite-clay composites. Different compositions of clay-magnetite compounds were investigated to study the magnetic properties of the samples. According to the study, with the increasing of magnetite in the composition the magnetic properties increase. However, increasing the magnetite in the composition leads to lose the stability of the suspension. The stability of the suspension also investigated by measuring of the size of the particles. Depending on the findings of the study 20% magnetite-clay composition was the optimal value for the magnetic solution.
