摘要

The present invention relates to a process for the production of a porous, ceramic or vitreous material, from powder materials, preferably waste materials. According to a different embodiment, the present invention relates to a process for applying a coating of a porous material obtained from powder materials, preferably waste materials, to a pre-existing solid surface. The alternative processes according to the present invention provide for the steps of mixing under stirring a solvent, a binder, and a cross-linking agent until a gelling solution is obtained, and adding to said solution a powder material, and a chemical leavening agent to obtain a homogeneous mixture, which is heated at low temperature until a porous solid material is obtained. The present invention also relates to a porous, ceramic or vitreous material, comprising a generally amorphous phase, in turn comprising inorganic oxides, and a binder, obtainable by a process according to the invention, suitable for the capture of atmospheric particulate matter and organic contaminants.
