Composite article, alloy and method

A process for producing a porous ceramic, ceramic composite or metal-ceramic composite structure by combustion synthesis wherein a foamed polymer shape is impregnated with a slurry of ceramic precursors and ignited to initiate combustion synthesis, thereby obtaining a ceramic, ceramic composite or metal-ceramic composite article having interconnected porosity. Ceramic composite filters having improved strength, toughness and thermal shock resistance are provided, with the ceramic composite being an oxide and a nonoxide.

Process for producing a porous ceramic and porous ceramic composite

A dimensionally stable combustion synthesis product of a composition containing at least 20% by weight of a particulate combustible material; at least 15% by weight of a particulate filler material capable of providing desired mechanical and electrical properties; and up to 35% by weight of a particulate inorganic binder having a melting point lower than the combustion synthesis temperature. Electrodes suitable for electrochemical processing are a preferred product form, particularly electrodes for use in the electrowinning of aluminum from its oxide.

Composite electrode for electrochemical processing and method for using

The present invention relates to a method of making metal ceramic composites and the metal ceramic compositions and articles made therefrom, especially net-shaped articles having a wide variety of applications. The present invention involves preparing a combustion synthesis mixture comprising at least one substance containing a combustible mixture of powders and at least one low-melting metal, forming this mixture into a desired final shape in a die, and carrying out a combustion synthesis therewith. Ceramic or metallic reinforcements may be incorporated in the combustion synthesis. The present invention allows the control of porosity in the resultant composite compositions and can result in composites having high toughness characteristics.
