| Abstract: | With the furnace dust produced in steel making as raw material hard barium ferrites are made.The required crystal phase of these ferrites is obtained through the following process:doping,control of air and temperature,activation of the raw material,and the crystal phase transformation.The action and interaction of different factors in the preparation of the ferrites are explained by methods such as X ray analysis.electron diffraction,and microphotography. |
