Soft magnetic materialsHaving lowcoercivityAnd highpermeabilityofmagnetic materials.soft magnetic materialEasy to magnetize and also easy todemagnetizationWidely used forElectrotechnical equipmentAnd in electronic devices.itsThe development has promoted the development of emerging industries such as mobile communication, photovoltaic new energy, new energy vehicles and their charging facilities, cloud computing, big data, artificial intelligence, etc. in China, and has also enabled traditional industries such as household appliances, computers and their peripherals, energy-saving lighting, electromagnetic compatibility, and industrial automation to remain prosperous for a long time.

High purity iron oxide is the main raw material for producing soft magnetic materials, and the main component in iron oxide isandThe content of impurity elements directly affects the quality and grade of the product. The main content of iron oxide in this material is 99.x%ImpuritiesAl₂O₃Waiting for low content 0.00x％Traditional adoptionICPMethod for detecting iron oxideSO₄ ^2-TheCaOTheSiO₂TheAl₂O₃TheMnO, determined by chemical methodFe₂O₃ TheCl^-The content. The entire analysis process is labor-intensive, time-consuming, and prone to human error.XRFLaw has the abilityDetermine the main amount of iron oxide and trace impurities, andThe advantages of simplicity, speed, low cost, and minimal human error are widely used in the analysis of soft magnetic ferrite.

Due to the high content of major elements 99．x%Requires a high level of analytical accuracy, while the secondary elements are all light elements,SiO2TheA12O3Only a few dozenppmIt also requires continuous determination of multiple elements, and powder compression method is an optional method.Due to the low rate of direct compression molding and poor precision of the main elements, the addition of binders is adopted.
