Abstract
This study uses pure materials or waste batteries to produce a nanoscale Mn–Zn ferrite. Acid is used to dissolve the battery into solution and then co-precipitation is used to produce nanoscale ferrite. When the calcination temperature in an air atmosphere exceeds 600 °C, α-Fe2O3 is generated and there is a decrease in the saturated magnetization. Using waste batteries to produce [Mn0.54Zn0.46]Fe2O4 at a pH of 10, the saturated magnetization is 62.85 M (emu/g), which is optimal. At a pH of 10, the particulate diameter is largest, at about 40 nm. The stronger the crystal phase of Mn–Zn ferrite, the greater is the saturated magnetization. The ferrite crystal phase is analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM) and a vibrating sample magnetometer (VSM). The stronger the crystal phase, the larger is the average particulate diameter. The magnetic properties, the particulate diameter and the magnetic flux density of ferrite powders that are prepared under different conditions are studied. [MnxZn1−x]Fe2O4 ferrite powders can be used as an iron core and as resonance imaging materials.
Highlights
Ferrite cores are a vital inductive component in motors for computer, communication and consumer Electronics (3C) products, so they are an important raw material for the industry.Traditional production methods use MnO2, ZnO and Fe2 O3 as raw materials, and a solid-state reaction is initiated
It is seen that the particulate diameter is different for different crystal phases
We show the saturated magnetization for a Ni–Zn
Summary
Ferrite cores are a vital inductive component in motors for computer, communication and consumer Electronics (3C) products, so they are an important raw material for the industry. When the raw materials are mixed, sintered and ground, a powder is produced. Waste batteries can be used as a raw material to produce of Zn–Mn ferrite. The recovery of Mn from Zn–Mn and Zn–C battery waste has been the subject of studies [19,20,21,22]. In this experiment, co-precipitation at different pH values (pH of 6–12) and different sintering temperatures (0–1200 ◦ C) is used to synthesize [Mnx Zn1−x ]Fe2 O4 nano-ferrite powder. Mn–Zn ferrites are prepared under different conditions and the differences in the physical properties and electromagnetic properties of the nano-powders that are produced using pure material and waste batteries are determined
