    Abstract: PURPOSE: A preparation method of ceramic gel compact is provided, which controls gelation-inducing time easily without lowering the physical properties of gel compact by adding peroxide-based polymerization initiator and gelation-inducing time increaser to ceramic dispersing agent for gel casting. CONSTITUTION: The preparation method comprises the steps of: dispersing at least one ceramic powder selected from Al2O3, ZrO2, ZnO, Si3N4 and SiC, into a solution of at least one organic radical monomer selected from acryl amide, methylacryl amide and hydroxymethyl acryl amide; adding one or more of peroxide-based polymerization initiator selected from ammonium persulfate, sodium persulfate, magnesium persulfate and hydrogen peroxide, and one or more of gelation-inducing time increaser selected from nitroxyl radicals, aliphatic alcohols and aqueous azos; degassing and pouring into a mold; forming a gel compact. The nitroxyl radical-based gelation-inducing time increaser, such as 2,2,6,6,-tetramethyl piperidine-1-oxyl(TEMPO), 4-hydroxy-2,2,6,6,-tetramethyl piperidine-1-oxyl(HTEMPO), is used in a range of 5-500 ppm, based on the total amount of dispersed solution. The aliphatic alcohol-based gelation-inducing time increaser, such as methyl alcohol, ethyl alcohol, butyl alcohol, etc, is used in a range of 5-20%, based on the total amount of dispersed solution. The aqueous azo-based gelation-inducing time increaser, such as azobis(2-amidinopropane) hydrochlorate, is used within the range of 1:9-9:1(in a weight ratio), based on the peroxide-based polymerization initiator.
