Method for manufacturing a ceramic article

Abstract

This invention relates to a method for manufacturing ceramic articles, the method comprising the following steps: (step 1) providing at least one ceramic structure obtained by using at least one ceramic compound and at least one binder through a binder jet molding 3D ceramic printer, wherein the ceramic structure has an open porosity of at least 35.00%; (step 2) providing at least one slurry S1, the slurry S1 comprising solid particles [hereinafter referred to as solid particles A] and at least one liquid phase, wherein the solid particles A have a d50 particle size value equal to or greater than 1.00µm and less than 30.00µm; and (step 3) immersing at least a portion of the ceramic structure into the slurry S1 at least once, thereby causing the solid particles A to at least partially penetrate into the open pores of the ceramic structure [hereinafter referred to as the penetrated ceramic structure]. The present invention relates to a method for manufacturing a ceramic article, which method comprises the steps of (Step 1) providing at least one ceramic structure obtained by a binder jetting 3D ceramic printer using at least one ceramic compound and at least one binder, wherein said ceramic structure has an open porosity of at least 35.00 % and (Step 2) providing at least one slurry S1 comprising solid particles [solid particles A, herein after] and at least one liquid phase, wherein said solid particles A have a d50 particle size value equal or more than 1.00 µm and less than 30.00 µm and (Step 3) at least one dipping of at least part of the ceramic structure in the slurry S1 thereby infiltrating at least partly the open pores of the ceramic structure with the solid particles A [infiltrated ceramic structure, herein after]
