The Main Component Of C-5 Magnets
Aug 09, 2018

A magnet, also known as a magnet, refers to an object or material that has a magnetic field around and within itself. It is divided into two categories, natural and artificial. Artificial magnets are usually made of a metal alloy and have strong magnetism. It can also be divided into "permanent magnets" and "non-permanent magnets", namely "hard magnetic" and "soft magnetic". The main component of natural magnet: triiron tetroxide, chemical formula Fe3O4, often called "magnetic iron oxide". A black crystal with magnetic properties. It can be regarded as a compound composed of ferrous oxide and iron oxide. Because there are two different valence ions in the crystal of ferroferric oxide, one third of them are Fe2+ and two thirds are Fe3+, which is a complex compound. It is insoluble in water and does not react with water. Reacts with acid and is insoluble in alkali. Primarily used in the manufacture of primers and topcoats, magnetic materials for the electronics industry, and rust inhibitors for the construction industry.
