    摘要： The invention provides a method of preparing a dispersion of a fumed metal oxide in a liquid carrier comprising the following sequential steps: (a) providing a liquid carrier at a pH that effects dissolution of the metal oxide at a rate the same as or greater than the metal oxide dissolution rate in water at a pH of about 8, (b) mixing with the liquid carrier, in any order, one or more aliquots of both a fumed metal oxide and a metal ion source to form a dispersion, such that the dispertion does not coagulate, and (c) optionally adjusting the pH of the dispersion to the pH of the liquid carrier in step (a). The method allows for the preparation of the dispersion to be done with a high solids loading and at a high pH. Furthermore, the dispersion can have a shelf-life of at least about 1 hour or more at 25°C.

    摘要： Sputtering targets and methods of making sputtering targets are described. The method includes the steps of: providing a sputtering metal workpiece made of a valve metal; transverse cold-rolling the sputtering metal workpiece to obtain a rolled workpiece; and cold-working the rolled workpiece to obtain a shaped workpiece. The sputtering targets exhibits a substantially consistent grain structure and/or texture on at least the sidewalls.

    摘要： A process to purify and classify a dispersion containing stabilized particles having counterions and ions as well as free species is disclosed. The solution may comprise an aqueous media, a solvent media, or a combination of both and can include more than one type of aqueous and/or solvent solutions. The process includes at least the steps, in any order, of substantially removing the particles having sizes above about 1 micron, preferably above 0.5 micron; substantially removing the free species; and exchanging at least a portion of the counterions that are a part of the stabilized particles. The process disclosed is especially useful in purifying dispersions where the ionic stabilized colloidal particles are carbon black having attached organic groups comprising at least one ionic group, or at least one ionizable group, or mixtures thereof.
