…Although it is a mechanical mixture of two finely mixed crystals, it behaves like a pure crystal, maintaining a constant temperature when melting. The melting temperature at which it does so is called the eutectic point. In a solution with a non-eutectic composition, pure component A or B precipitates first, and as the temperature decreases, the amount of pure component A or B gradually increases, and finally the eutectic mixture precipitates at the eutectic point. … *Some of the terminology that mentions "eutectic point" is listed below.

…2種の結晶が細かく混合してできた機械的混合物でありながら,溶けるときにも一定温度を保つ純粋結晶のごとき挙動を示す。その融解温度を共晶点または共融点eutectic pointと呼ぶ。共融組成以外の溶液では最初に純成分AまたはBが析出し,温度の低下とともにしだいにその量を増しながら最終的に共融点で共融混合物が析出する。… ※「eutectic point」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
