초록

Measurements of proton adsorption density have been conducted in preparing alumina suspensions with aqueous solutions of HCL, HNO3, H2SO4 and H3PO4 And effects of anion acid concentration proton adsorption density and solid loading on the viscosity of the alumina suspensions have been investigated. Aqueous solutions of HCl. or HNO3 were suitable for the preparation of highly concentrated suspensions as the generation of surface charge on alumina particles was depressed by the specific adsorption of {{{{ {SO }`_{4 } ^{2- } }} and {{{{ { PO}`_{4 } ^{3- } }} Optimum conditions for maximizing solid loading were dependent upon proton adsorption density and acid concentration.
