N2 - The invention relates to a method for producing an in particular porous molded ceramic article, which molded ceramic article is optionally reinforced with fibers and/or a semi-finished textile product such as woven fabric, wherein a powder A and at least one further powder B are suspended in a liquid, after which a molded article is formed from the suspension produced in this manner optionally in combination with fibers and/or a semi-finished textile product and the molded article is optionally sintered. It is provided according to the invention that the powders A and B are suspended approximately at a pH value of the liquid at which a viscosity minimum of the suspension is given, whereby high solids contents in the suspension can be adjusted with low viscosities. This makes possible a rapid production of largely crack-free molded articles with advantageously low-defect structures.
