초록 ▼

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.

1. A method of making a metal oxide article, comprising the steps of:pressing powder to form a compact, said powder consisting essentially of a first oxide of the metal; and subjecting said compact to a heat treatment, said heat treatment causing said powder to sinter into a unitary body and resulting in the transformation of at least a portion of said first oxide to a second oxide of the metal; wherein said step of subjecting said compact to said heat treatment comprises the steps of: subjecting said compact to a first temperature such that at least a portion of said first oxide transforms to said second oxide; and subjecting said compact to a second temperature after said step of subjecting said compact to said first temperature, thus causing at least a portion of said second oxide to transform to said first oxide; the resultant metal oxide article having an open interconnected pore structure.
