Preparation of Super-fine Cerium Oxide Using Mechanically Chemical Method

摘要

The cerium oxide powder has been modified with mechanically chemical method. The effect of modifier, reaction time, calcine temperature, and amount of additives on the particle size, density, and hardness of super-fine cerium oxide was investigated. The complex super-fine cerium oxide powder was prepared, whose physical state and feature were characterized. The results show that modifier and powder may interact, which improves the properties of super-fine cerium oxide.
