摘要： 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%.

摘要： PURPOSE: A method for manufacturing high strength and low temperature sintered ceramic is provided to secure the high sintering density and the high intensity at low sintering temperature by implementing a sintering process at low temperature of 1000 to 1400 degrees Celsius without the growth of grain. CONSTITUTION: A method for manufacturing thigh strength and low temperature sintered ceramic includes the following: Alumina, water, a binder, and a dispersing agent are mixed to obtain slurry. The purity of the alumina is more than or equal to 99.99 wt%. The slurry is shaped using a slip casting method, a doctor blade method, a cold isostatic pressing method, or a hot isostatic pressing method. The shaped slurry is thermally treated at temperature between 800 and 1500 degrees Celsius for 1 to 10 hours.
