Abstract: An open cell porous material and a method for producing it is provided. The porous material of the present invention is generally composed of particles of at least one inorganic material bonded together by a brazing agent, generally provided as inorganic brazing alloy particles. The porous material is produced by heating a mixture comprising inorganic brazing alloy particles having a first melting temperature, inorganic particles having a second melting temperature higher than the first melting temperature, a binding agent having a decomposition temperature lower than the first melting temperature and preferably a foaming agent. In practice, the mixture is heated to induce foaming thereof via the foaming agent. The solid foamed structure is then heated at the decomposition temperature to substantially eliminate the binder.
