엑스선 회절

위키백과, 우리 모두의 백과사전.

X선을 결정에 조사하면 브래그 법칙을 만족시킨 방향에만 X선이 회절되어 결정구조를 반영시킨 패턴이 생긴다.

엑스선 회절(X‐ray diffraction, XRD) 또는 X선 회절결정격자를 통과한 X선회절을 나타낸 영상이다.

1912년 막스 폰 라우에가 이 현상을 발견하여 X선이 사실은 파장이 짧은 전자기파라는 것을 밝혔다.

거꾸로 이 현상을 이용해 물질의 결정 구조를 조사하는 것이 가능하다. 이러한 X선 회절의 결과를 해석해 결정 내부의 원자가 어떤 배열을 하고 있는가를 밝히는 방법을 'X선 결정구조해석' 또는 'X선 회절법'이라 한다. 이 외에 회절현상을 이용한 결정구조해석의 방법으로 전자회절법, 중성자회절법 등이 있다.

X선 회절 결정학은 광물학[1], 재료과학[2], 촉매작용[3][4][5][6], 생화학[7][8][9][10][11], 예술 등 다양한 과학 분야에서 사용됩니다. 역사[12][13][14][15] 그리고 고고학에서도[16].
