    • Metal oxide-containing dispersions and methods of producing the same are provided. Generally, dispersions according to the invention comprise respective quantities of surfactant, metal oxide, and carrier. Methods according to the invention generally comprise providing a quantity of metal oxide particles of having a desired size suitable for being dispersed in a carrier with the aid of a surfactant. If necessary, the metal oxide particles may be mixed with the carrier and then undergo a pulverization step whereby the average particle size is reduced to the desired level, or the metal oxide particles may be pulverized prior to addition of the carrier. Dispersions made in accordance with the present invention generally exhibit excellent stability in that the metal oxide particles remain suspended in the dispersion for at least about one month.
    • 提供含金属氧化物的分散体及其制备方法。 通常,根据本发明的分散体包含各自量的表面活性剂,金属氧化物和载体。 根据本发明的方法通常包括提供一定量的具有适于在表面活性剂的帮助下分散在载体中的所需尺寸的金属氧化物颗粒。 如果需要,可以将金属氧化物颗粒与载体混合,然后进行粉碎步骤,由此将平均粒径降低到所需的水平,或者可以在添加载体之前将金属氧化物颗粒粉碎。 根据本发明制备的分散体通常表现出优异的稳定性,因为金属氧化物颗粒保持悬浮在分散体中至少约一个月。
