| 摘要 |
The present invention relates to a method for producing sulphate-poor, polynucleate aluminium hydroxide sulphate complexes of the general formula [Al(OH)x(SO4)y(H2O)z]n in which n is an integer; x is 0.75-2.0; y is 0.5-1.12; x+2y is 3; z is 1.5-4 when the product is in solid form, and z>>4 when the product is in the form of an aqueous solution, an amorphous aluminium hydroxide being admixed with aluminium sulphate and/or sulphuric acid to y=0.5-1.12; preferably 0.5-0.75. |
