Method for producing naon-magnetic liquid

A method for preparing a type of nanomagnetic liquid includes preparing nanomagnetic particles of Fe3O4 by utilizing liquid phase coprecipitation first, then placing them in to acid liquid for carrying out chemical reaction to generate Fe3+ and Fe2+ being used as peptizer, peptizing nanoparticles to...

Zusammenfassung:	A method for preparing a type of nanomagnetic liquid includes preparing nanomagnetic particles of Fe3O4 by utilizing liquid phase coprecipitation first, then placing them in to acid liquid for carrying out chemical reaction to generate Fe3+ and Fe2+ being used as peptizer, peptizing nanoparticles to form absorbed electric double layer on particle surface for preventing agglomeration between particles to obtain stable and scattered nanomagnetic liquid .
