| description | The present invention relates to a method for producing alumina with high purity and high density using a high temperature vacuum sintering furnace. The method includes: a first process of synthesizing aluminum hydroxide (Al(OH)_3, ATH); a second process of separating aluminum hydroxide (ATH) from the synthesized aluminum hydroxide (Al(OH)_3, ATH) using a solid-liquid separator; and a third process of producing alumina (Al_2O_3) using the aluminum hydroxide (ATH). According to the method, purity and the yield of aluminum hydroxide as a raw material for alumina are increased. Therefore, the amount of alumina production is increased, and environmental pollution can be reduced. |
