The results showed that the hollow nanospheres were 65 nm in sizes, which was smaller than that of the original CeO2 nanospheres. The Ce(subscript 1-x)TiO2 hollow nanospheres were face-centered cubic structure as the same as CeO2 nanospheres.

结果表明，Ce(下标 1-x)TiO2纳米空心球的粒径为65 nm，小于初始状态的CeO2纳米球，并且Ce(下标 1-x)TiO2纳米空心球的结构与前驱体CeO2晶体结构相同，均为面心立方结构。

The results show that:(1) Light-calcined MgO powders prepared with nature magnesite or Mg2 both are of face-centered cubic structure.

结果发现：水化前后得到的都是面心立方晶体结构的MgO，但水化前得到的轻烧MgO中仍存在官能团CO32-的残留物，而水化后得到的轻烧MgO中不存在CO32-，而且颗粒变得较易破碎，大大减少了细磨时间；再者，水化后的轻烧MgO活性较高，加上Mg2在分解过程中残留的水分对MgO 的烧结起催化作用，因此，使其经高温锻烧制得的烧结镁砂的开口气孔率由水化前的2.0%下降到0.6%，闭口气孔率由水化前的6.1%下降到2.8%，体积密度由水化前的3.29g/cm3提高到3.46g/cm3。
