The invention discloses a method for rapidly curing ceramic slurry. The method comprises the following steps: firstly, mixing ceramic powder, a dispersant and water and sufficiently carrying out ball milling to prepare the ceramic slurry with a negatively-charged particle surface; then, adding iodate of high-valence metal cations and carrying out the ball milling; stirring the obtained slurry under a vacuum condition and degassing; then adding an esters pH (Potential of Hydrogen) regulator; after uniformly stirring, injecting the slurry into a pore-free mold; storing the pore-free mold at 45 DEG C to 70 DEG C for 15 minutes to 45 minutes; de-molding to obtain a ceramic wet blank; drying the ceramic wet blank to obtain a dry blank; then putting the dry blank into a sintering furnace and sintering to obtain a sintered ceramic body. According to the method provided by the invention, the common effect of decomposing the iodate through temperature control to release the high-valence metal cations and decomposing and regulating the pH value to an isoelectric point through the esters pH regulator realizes rapid curing and molding of the ceramic slurry; the method has the advantages that the method is suitable for any ceramic slurry with negative charges, is rapid in curing speed, high in slurry molding efficiency, environment-friendly, excellent in performance and simple to operate, is convenient for large-scale production and the like.
