Abstract
A novel metal/ceramic hybrid material in which the void space of the ceramic is filled with metal. The metal may be bonded to the ceramic, for example by formation of a metal oxide. The metal may be introduced into the ceramic as small particles in a suspension then heated to melt the metal, allowing bonding to the ceramic or better filling of the void space. The hybrid material may be used in a variety of applications.
Claims19
A method of making a hybrid material comprising:
- providing a porous ceramic with a matrix of interconnected void space wherein the ceramic includes exposed surfaces comprising at least 50% silicon dioxide prior to introducing metal particles into the void space;
- introducing a fluid comprising the metal particles into the porous ceramic such that the metal particles flow throughout the interconnected void space of the ceramic;
- and
- heating the metal particles to cause the metal particles present in the interconnected void space of the ceramic to react with oxygen of the silicon dioxide of the ceramic to form a covalent bond between the metal and the ceramic.
