Description
또한, 본 발명에 사용되는 분말합성 반응기(6)는, 외부가열방식의 노(Furnace)로서, 일반적으로 석영관 또는 알루미나관등을 이용한 관상로(Tube Furnace)가 사용될 수 있다. 이 관상로는 코일형, 적외선 가열 등 다양한 발열체에 의해 외부에서 가열될 수 있으므로 관상로의 가열온도와 가열영역의 범위가 조절가능하며, 관상로 내에 온도구배(temperature gradient)를 부여할 수 있으므로, 이 관상로 내부로 주입된 전구체가 이 관상로를 통과하면서 열분해 되는 과정에서 다양한 제조공정 변수를 유도할 수 있는 장점이 있다.
