ABSTRACT:
A method for processing a ceramic powder suspension includes providing a dispersant having the following structure:wherein R1is an H+ion, an Na+ion, an NH4+ion or other cationic group; R2is an H+ion, an Na+ion. an NH4+ion or other cationic group; m is an integer from 10 to 5000 ; and n is an integer from 10 to 3000 . The dispersant is dissolved in a solvent. Ceramic powder is further added into the solvent with the dispersant.
