General description

Iron(II,III) oxide, also known as ferric ferrous oxide, with a purity of 99.99% trace metals basis, exhibits unique magnetic, electrical, and catalytic properties. It has density of 4.8-5.1 g/mL at 25 °C and melting point of 1538 °C , which indicates thermal stability and mechanical strength. In the field of biomedical applications, it has shown promise in magnetic resonance imaging (MRI) contrast agents and drug delivery systems due to its magnetic properties and biocompatibility. In the semiconductor industry, iron(II,III) oxide has been investigated for its potential use in spintronics and magnetic tunnel junctions, where its magnetic properties can be utilized for information storage and processing. Additionally, it is being explored for use as an anode material in lithium-ion batteries, offering high theoretical capacity and low cost due to its abundance.

Self-Propagating Reactions Induced by Mechanical Alloying

Mechanical alloying is a “brute force” method of affecting alloying and chemical reactions. The mixture of reactant powders and several balls are placed in the milling jar of a high-energy ball mill, for example, a shaker mill or a planetary mill.
