Abstract
The present invention relates to a ceramic foam structure characterized in that it is produced by using a reaction bonded power. The invention also relates to a method for producing a ceramic foam structure, characterized in that the method comprises the following steps: providing a reaction bonded power blend, producing a stable slurry of the powder blend in water or in a solvent, producing a foam, drying said foam, calcinating said foam, oxidizing said foam, and a final thermal treatment Using this method, ceramic foams having better mechanical properties compared to classical foams can be prepared.

A method for producing a ceramic foam structure, characterized in that the method comprises the following steps:
- providing a reaction bonded powder blend with metal and/or metal oxides,
- producing a stable slurry of the powder blend in water or in a solvent,
- producing a foam,
- drying said foam,
- calcinating said foam,
- oxidizing said foam through slow air heating up to a final temperature comprised between 900° C. and 1100° C., and
- a final thermal treatment.
