The invention concerns a method for producing porous ceramic materials that provides the advantage of controlling and adjusting the porous structure according to the type of application desired. This method combines three techniques that make it possible to generate a multimodal porosity inside a ceramic body that are based on the thermal decomposition of an aluminum hydroxide on the calcination of a pore-forming agent and, lastly, on the aeration of a ceramic suspension by means of a foaming agent. The invention also concerns the refractory porous material obtained using this method.
