CALCINED CALCIUM AND PRODUCTION METHOD THEREOF
To provide calcined calcium that can be easily pulverized into fine powder without being pulverized with an expensive and/or dedicated mill.SOLUTION: A production method of calcined calcium is the method that produces the calcined calcium using at least one start material selected from shells, egg shells, sea urchin shells, corals, and crustacea. The production method includes in order: (A) a primary calcination process of calcining the start material at 1100°C or higher and for four hours or longer; (B) a process of executing natural cooling of the calcined primary burned product up to the ambient temperature; (C) a process of agitating and/or mixing the primary burned product so as to be substantially uniform; (D) a secondary calcination process of calcining the primary burned product at 1100°C or higher and for two hours or longer; and (E) a process of executing natural cooling of the calcined secondary burned product up to the ambient temperature.SELECTED DRAWING: None
【課題】高価および／または専用の粉砕機を用いて粉砕することなく、容易に微粉末に粉砕することが可能な焼成カルシウムを提供する。【解決手段】貝殻、卵殻、ウニ殻、珊瑚、甲殻から選ばれる少なくとも１つの開始材料から焼成カルシウムを製造する方法であって、順番に、（Ａ）前記開始材料を１１００℃以上で４時間以上焼成する一次焼成工程、（Ｂ）焼成された一次焼成物を外気温まで自然冷却させる工程、（Ｃ）一次焼成物を実質的に均等になるよう撹拌および／または混合する工程、（Ｄ）一次焼成物を１１００℃以上で２時間以上焼成する二次焼成工程、（Ｅ）焼成された二次焼成物を外気温まで自然冷却させる工程、を含む焼成カルシウムの製造方法。【選択図】なし
