    • PURPOSE: A manufacturing method of alumina ceramics is provided to obtain alumina ceramics with high density and strength. CONSTITUTION: A manufacturing method of alumina ceramics comprises: a step of wet mixing the raw material which comprises an alumina(Al2O3) raw material and a plasticized alumina raw material, to obtain slurry; a step of assembling a mold for filter pressing; a step of injecting the slurry into the mold; a step of pressurizing the slurry; a step of demolding a product from the mold; a step of drying the molding product; a step of sintering the molded product. The comprised amounts of the plasticized alumina raw material and the alumina raw material are respectively 60-80 wt% and 20-40 wt%.
