  • TREATED TITANIUM DIOXIDE PIGMENT WITH HIGH MAGNESIUM OXIDE ADDITION, PROCESS OF MAKING THEREOF AND USE THEREOF IN PAPER MANUFACTURE
    Publication number: 20220333310
    Abstract: Process for the surface treatment of a titanium dioxide pigment, characterized in that it comprises the following steps: an aqueous suspension of titanium dioxide pigments is formed, in a first step, a layer of alumina phosphate is precipitated on the surface of the pigment, in a second step, a layer of alumina is precipitated over the first layer of alumina phosphate, and in a third step, a layer of magnesium oxide and alumina is precipitated on the layer of alumina. Also included are titanium dioxide pigments made by the disclosed process and method using said pigments in paper manufacturing.
