摘要
建立了拜耳法生产砂状氧化铝分解过程中最佳分解温度Ｔｏｐｔ与溶液氧化铝浓度动的关系式。实验用附聚──粘结长大工艺，按最佳分解温度制度进行分解，所得产品砂状氧化铝强度高，ＡＩ：８．３２～１４．０２％；溶液分解率η：４５％左右。
The opitimum temperature is found as a function of the alumina concentration in Bayer precipitation. According to the mechanism of the seed Agglomeration - Growth at optimum temperature, the results of the experimental study are as follows: the coefficient of attrition of sandy alumina AI: 8. 32￣14. 02% ; and the precipitation efficiency of the seeded pregnant aluminate solution (η) about 45%.
