    How to prepare ferroferric oxide magnetic fluid in the laboratory

    Preparation of kerosene-based magnetic fluid of Fe3O4 In this experiment, analytically pure ferric chloride, ferric chloride and ammonia (NH3 content 25%) were used to prepare magnetic particles of Fe3O4 according to chemical coprecipitation method. The chemical reaction equation is 2FeCl3·6H2O+FeCl2·4H2O+8NH3·H2O= Fe3O4+8NH4Cl+24H2O (1) In the dissolution process, FeCl2·4H2O blue-green crystals a...

    Why is Fe3O4 magnetic and how is magnetic generated?

    Ferric oxide Nanopowder is a crystal, and its internal molecules are arranged in a regular manner, and the molecular current orientation is uniform, resulting in magnetic properties. When the magnet is brought close to the ferromagnetic substance, it is magnetically affected by the magnet, and the internal molecular current of the ferromagnetic substance tends to be regularly oriented and mag...

    What application can nano silicon powder done as anode material in lithium battery

    As the anode material of lithium ion battery, silicon nanopowder has the highest theoretical specific capacity (up to 4200 mAh/g), which is much higher than the carbon powder widely used at present, but the biggest disadvantage of silicon powder as the negative electrode of lithium ion battery is the process of alloying with lithium. In the case of a large volume change, the active material is det...

    Guidelines for the use of silicon carbide whiskers

    1)Silicon carbide whiskers should be pre-dispersed as much as possible before use. They should be mechanically and ultrasonically dispersed with water, ethanol, etc., and then mixed with the matrix material. 2) The amount of silicon carbide whiskers added to the material is not as high as possible, and there is usually an optimum value. Ordinary ceramics are generally added in an amount of 1-10%. ...
