摘要
The invention relates to a method for preparing an aqueous clay paste, characterized in that it includes at least the steps of: preparing a first mixture of clay and phosphoric acid and kneading; and adding hydrated sodium silicate (Na 2 O) - (SiO 2 ) - (H 2 O) to said mixture, preferably having a 30% content of SiO 2 , also preferably in a phosphoric acid and sodium silicate ratio of at least 1:3 by weight; and kneading the final mixture. Said method includes different variants, depending on the content of water in the clay starter. The invention likewise relates to a method for manufacturing ceramic materials in which the aqueous clay paste is used as a raw material, which are obtainable by the method described herein, as well as to the aqueous clay paste and the ceramic material produced by both methods. The invention additionally relates to the use of the aqueous clay paste for manufacturing ceramic materials.
