Patent
·
OSTI ID:6480809
This patent describes a method of making a phosphated alumina comprising: (a) calcining alumina at a temperature of about 450/sup 0/C to about 900/sup 0/C; and (b) thereafter treating the thus calcined alumina with a phosphating agent selected from the group consisting of orthophosphoric acid, orthophosphates, POCl/sub 3/, PCl/sub 3/, phosphorous acid and NH/sub 4/H/sub 2/PO/sub 3/ to give a surface treatment wherein the atom ratio P/Al is in the range of about 0.2:1 to 2:1.
