Note: when the mass fraction of insoluble, ferrum, arsenium and plumbum of liquid products listed in the above table respectively refers to that the content of Al2O310% is not equal to 10%, corresponding mass fraction should be calculated by converting the actual content to Al2O310% product proportion. | ||||||||
