ABSTRACT:
A method is provided of crystallizing strong-bound zeolites on the surfaces of a monolithic ceramic substrate by hydrothermally treating the substrate, in the presence of active silica, with a caustic bath to zeolitize the silica. According to various embodiments of the invention, the active silica can be present as a component of the caustic bath, in the form of a dried coating pre-deposited on the substrate, or as a separate phase of the monolithic substrate, homogeneous dispersed within the ceramic material.
