Abstract: |
|||
| A process for preparing M-type ferrite nanoparticles by complexing citric acid uses iron nitrate, barium carbonate, strontium carbonate, citric acid and/or glycol, and includes such steps as depositing iron nitrate to obtain Fe(OH)3, repeatedly washing, sol-gel treating, and high-temp (700-1100 deg.C) calcining. | |||
