PURPOSE: A ceramics forming method using aqueous amino acid solution is provided which enables to form large-sized ceramics with complicated shapes due to high forming density and forming strength. CONSTITUTION: The forming method comprises the steps of: preparing each slurry by adding ceramic powder, such as, oxide(Al2O3, SiC, Si3N4, etc.) or non-oxide, to 2-10wt.% of amino acid solution and 0.5-1.5wt.% of hardening agent in one(5a) and the other(5b) of a first stirring vessel, respectively, and dispersing each slurry by adding dispersant less than 1wt.%; mixing together at 60-90deg.C in a second stirring vessel; defoaming; casting.
