每个基因是打开或关闭的开关 - The research firstly showed that the - al _ 2o _ 3 powder obtained by directly calcining the aach at 1150 owned a bad microstructure
研究发现，通过直接在1150煅烧该前驱体不能获得无团聚、粒径较小的- al _ 2o _ 3纳米粉体。 - The results show that the a - phase - transformation of pure aach can be completed by heating at 1200 ? for two hours . but under this temperature , the alumina particles will be sintered together , which can lead to the formation of bough - like structures . and these bough - like structure will make the powder difficult to be dispersed
接着对碳酸铝铵进行了焙烧实验，研究了其在升温过程中的相变行为，结果表明：纯aach在1200保温1 . 5h的情况下才能100转变为氧化铝，而在这样高的温度下，粒子之间会形成烧结颈，从而使粉体产物在形貌上出现所谓“树枝状”结构，给粉体使用时的分散带来了困难。
