Process for producing rigid reticulated articles |
摘要 |
A process for producing a rigid reticulated article involves coating a reticulated substrate which has open, interconnected porosity with a first dispersion comprising a ceramic or metal powder to form a first coating thereon; drying the coated reticulated substrate; contacting the coated reticulated substrate with one or more additional dispersions in succession to form one or more additional coatings thereon; drying the additional coatings between the steps of contacting; heating the coated reticulated substrate to pyrolyze organic components; and sintering the coated reticulated substrate to form a reticulated article, wherein each dispersion has a viscosity less than that of all preceding dispersions. A rigid reticulated article includes inner, intermediate and outer sintered layers of material in which the inner and outer layers are of different composition and the intermediate layer is a composite of the inner and outer layers.
