備注

1、粒度檢測(cè)因設(shè)備不同，數(shù)據(jù)有差別。The data of particle size testing vary with different equipment.

2、氧化鋁主要雜質(zhì)Na₂O、K₂O、SiO₂、Fe₂O₃按照國(guó)際檢測(cè)，其余微量元素用ICP。

The main impurity NA2O K2O SIO2 fe2o3 in alumina was determined according to the international standard，The rest of the micronutrient are in ICP.

3、其余指標(biāo)因檢測(cè)方法不同而異。The other indexes varied with different detection methods.
