Study program:
Minerology and Crystallography (V semester -BsC) |
|
Name of subject: General Crystallography |
Instructors:
Prof. Sabina Kovač |
|
Status: Compulsory |
|
ECTS: 5 |
|
Prerequisites: General Mineralogy, Mineral Classification, Mathematics 1 |
Course Objectives:
The purpose of the course is that students acquire basic crystallographic education in terms of external and internal symmetry, which is a consequence of the periodicity of the crystal structure of minerals and synthetic materials, and that they can interpret the results obtained by the X-ray diffraction method on polycrystalline material. |
Learning Outcomes:
During this course, students will learn: elemental macro-symmetry operations. By applying them, they will be able to determine the symmetry of crystal models or crystals; they will be classified into one of 7 crystal systems and 32 crystal classes. Students will learn about basic structural types, about X-ray diffraction on polycrystalline material and interpretation of powder diagram. |
Content:
