Provided here is a method of producing a monolithic body from a porous matrix, comprising: (i) providing a porous matrix having interstitial spaces and comprising at least a first reactant; (ii) contacting the porous matrix with an infiltrating medium that carries at least a second reactant; (iii) allowing the infiltrating medium to infiltrate at least a portion of the interstitial spaces of the porous matrix under conditions that promote a reaction between the at least first reactant and the at least sec-ond reactant to provide at least a first product; and (iv) allowing the at least first product to form and fill at least a portion of the interstitial spaces of the porous matrix, thereby producing a monolithic body, wherein the monolithic body does not comprise barium titanate.

L'invention concerne un procédé de production d'un corps monolithique à partir d'une matrice poreuse, consistant: (i) à utiliser une matrice poreuse présentant des espaces interstitiels et comprenant au moins un premier réactif, (ii) à mettre en contact la matrice poreuse avec un milieu d'infiltration qui porte au moins un second réactif; (iii) à permettre au milieu d'infiltration d'infiltrer au moins une partie des espaces interstitiels de la matrice poreuse dans des conditions qui favorisent une réaction entre le ou les premiers réactifs et le ou les seconds réactifs pour produire au moins un premier produit; et (iv) à permettre au premier produit ou aux premiers produits de former et de remplir au moins une partie des espaces interstitiels de la matrice poreuse, ce qui produit ainsi un corps monolithique, le corps monolithique ne comprenant pas de titanate de baryum.
