Function and development history of high purity iron
High purity iron is an important material for preparing magnetic recording media, magnetic recording heads, photoelectric devices and magnetic sensors. The new environmentally friendly semiconductor material B-FeSi2 requires higher purity of iron.Before that, High purity Iron The market has also soared for a time, which has attracted the attention of a wide range of investors. https://www.slhpureiron.net
High purity iron also has many unique properties, such as insoluble in hydrochloric acid and sulfuric acid, but soluble in nitric acid; It is difficult to cut high-purity iron ingots with traditional saw blades. High purity Fe-Cr alloy ingot is a structural-functional integrated material with incredible plasticity, strength, corrosion resistance, low expansion coefficient and high thermal conductivity.
Because iron itself is non-toxic, rich in resources and low in price, and iron silicide can be used to manufacture light-emitting elements in the infrared field, scientists are studying and developing high-purity iron as an optical semiconductor material.
In view of the important application and potential application value of high-purity iron, the preparation and research of high-purity iron has become a hot spot in the research of high-purity metals.
In the middle and late 1990s, research on the preparation technology of high-purity iron was widely carried out in the world, including Japan, France, Germany and the United States. Since 1994, seven international conferences on high purity metals (UHPM) have been held.
The research activities of high-purity iron in Japan have also been valued and funded by a large number of enterprises, research institutes and government agencies, and many important achievements have been made. They have successfully extracted iron with a purity of 6N. At present, the preparation of high-purity iron is still in the laboratory stage, and how to industrialize it is a direction that needs to be worked hard in the future.
