| 1. | By using the method of burning , we fabricated the ceramic powder of al2o3 , and discussed the effect of mole percentage of metal ions and urea on forming phases of al2o3 . we calculated the x - ray powder diffraction by scherrer formula , and we thought that the ceramic powder reaches nano order
采用燃烧法制备了al _ 2o _ 3陶瓷粉末，讨论了金属离子和尿素的摩尔比对al _ 2o _ 3成相的影响；对其x射线粉末衍射数据用scherrer公式计算得出所得al _ 2o _ 3陶瓷粉末已达到纳米量级。 |
