摘要：

The process of obtaining highly dispersed magnetite by precipitation from a solution of iron salts in water by hydroxide is investigated by the magnetometric method and the traditional physico-chemical methods. It is shown that the rate of magnetite formation, its dispersity and the presence of nonmagnetic compounds depend on the pH value of the reacting medium, the concentration of reagents, the nature of the precipitator and the temperature of synthesis. © 1990.
