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...

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...

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...
