WebCrystallography. Crystallography is the study of the arrangement of atoms in solids that are mostly in three dimensional pattern. [1] Before the development of X-ray crystallography, the study of crystals was based on their geometry. This involves measuring the angles of crystal faces, and establishing the symmetry of the crystal in … Web결정학(結晶学, crystallography)은 결정의 기하학적인 특징과 광학적인 성격, 물리적 성질, 화학적 성질 등을 연구하는 학문이다. 오늘날 결정학은 고체물리학, 화학에서 다루어진다.. 결정학에 관련된 과학자. 윌리엄 헨리 브래그; 윌리엄 로런스 …
