    摘要： Methods of making metal oxide articles, preferably iron oxide articles, and articles thereby produced. The method comprises the steps of slightly pressing powder to a compact, the powder consisting essentially of a first oxide of the metal; and subjecting the compact to a heat treatment that causes the powder to sinter into a unitary body and results in the transformation of at least a portion of the first oxide to a second oxide by oxidation or deoxidation during the heat treatment. In disclosed embodiments, the heat treatment is conducted either in air at atmospheric pressure or at a subatmospheric pressure. The method optionally includes more heating/cooling steps resulting in additional oxidation/deoxidation cycles. Sintered iron oxide articles of the invention have high mechanical strengths and interconnected pore structures, providing for efficient filtering of liquids and gases.

    摘要： A thin-walled monolithic iron oxide structure, and process for making such a structure, is disclosed. The structure comprises a monolithic iron oxide structure obtained from oxidizing a thin-walled iron-containing, preferably plain steel, structure at a temperature below the melting point of iron. The preferred wall thickness of the steel is less than about 0.3 mm. The preferred iron oxides of the invention are hematite, magnetite, and combinations thereof. The thin-walled structures of the invention have substantially the same physical shape as the iron starting structure. Thin-walled iron-oxide structures of the invention can be used in a wide variety of applications, including gas and liquid flow dividers, corrosion resistant components of automotive exhaust systems, catalytic supports, filters, thermal insulating materials, and sound insulating materials. Iron oxides of the invention consisting substantially of magnetite can be electrically heated and, therefore, can be applicable in applications such as electrically heated thermal insulation, electric heating of liquids and gases passing through channels, and incandescent devices. Additionally, combination structures using both magnetite and hematite can be fabricated.
