Abstract： |
The invention discloses a thermostable magnetic carrier and the method for preparation and the application, belonging to the art of magnetic composite material. The thermostable magnetic carrier is a core- shell structure of XmOn/ gamma- Fe2O3- SiO2. Prepare magnetic the core of gamma- Fe2O3- SiO2 composite oxide firstly, and then coat with multiple outer layer of XmOn oxide. The carrier can support plural of catalyst activity and absorption activity, and is characterized in that it is thermostable. And it is suit for the production or treatment of magnetic catalyst, magnetic absorption in high temperature. |
