| Abstract: |
| A study on surface modification of oxide iron powder with polyacrylate sodium and the titanate modifiers was carried out. The results were compared and the modified mechanism was analyzed. A compound modified method to add modifier to the oxide iron powders when intensive grinded by the planetary ball mill was conducted. The experiment indicates that the polyacrylate sodium and the titanate can both disperse the oxide iron powder notably; and the compound modified method can not only reach an excellent modification effect, but also can make the powders much finer. |
