Abstract
A porous ceramic substrate is disclosed that is fabricated from biosoluble ceramic fibers. Porosity and permeability of the substrate is provided by intertangled biosoluble fibers, that can be formed into a honeycomb form substrate through an extrusion process. The fibrous structure is formed from mixing biosoluble fibers with additives that include a bonding agent, and a fluid to provide an extrudable mixture. The structure is sintered at a temperature that exceeds the glass formation temperature of the bonding agent, but less than the maximum operational limits of the biosoluble fiber, to form a structure that has sufficient strength and porosity to provide for filtration and/or as a catalytic host.
