    摘要： A method for manufacturing high-purity alumina material is disclosed, which includes the steps of: reacting aluminum metal with a mixture of organic base and water to form aluminum hydroxide suspension; removing water by filtration to form aluminum hydroxide slurry, and drying/baking the slurry to form aluminum oxide powders. The method is amenable to mass production of high-purity aluminum oxide containing total silica and non-aluminum metal impurities less than 0.005% and having a bulk density higher than 3.0 g/cc. In addition, the invention also provides high-purity aluminum oxide prepared by using the method disclosed and bulk products prepared therefrom.

    摘要： The present invention is directed to a process for the preparation of crystalline anionic clay-containing bodies from sources comprising an aluminum source and a magnesium source comprising the steps of: a) preparing a precursor mixture, b) shaping the precursor mixture to obtain shaped- bodies, c) optionally thermally treating the shaped bodies, and d) aging to obtain crystalline anionic clay-containing bodies. The quintessence of the present invention is that the bodies are shaped prior to the forming of the crystalline anionic clay in said bodies. This results in very attrition resistant bodies, without the need to add a binder material.

    摘要： A method for processing ceramic slip into a filter cake suitable for further processing into electrical insulating bodies applies a D. C. power source across the press plates of a filter press during a portion of the pressing process. After a selected period of time the polarity of the source is reversed for a selected period.
