The "Inorganic Chemistry 2" course follows the courses "General and Inorganic Chemistry" and "Inorganic Chemistry 1 with Laboratory"; indeed, it concerns the study of the solid state both from the structural and microstructural point of view and introduces different experimental characterization techniques. The 5 credits are devoted to lectures (4 credits) and practical exercises (1 credit) conducted both in the classroom and in the research laboratories.



The course will introduce students to the knowledge of the structural chemistry of inorganic solids and of the structural (X-ray Diffraction), microstructural (optical and electronic microscopy), thermoanalytical (differential thermal analysis, thermogravimetry) and calorimetric characterization techniques for inorganic materials. The educational path has the aim of developing the ability to analyze critically experimental results in real cases.


The educational path of the course will lead to the knowledge of different aspects of the chemistry of inorganic crystalline solids (i.e oxides and alloys) starting from the structure up to their characterization. In addition to the crystalline structure, microstructural features will be discussed in relation to the knowledge of two-component phase diagrams. Some concepts introduced in the course of Inorganic Chemistry 1 which will be studied, expanded and discussed in the classroom.

During the lectures, both Power Point and video presentations will be employed to increase the students’ engagement and improve their learning process. There will also be some practical activity in the classroom and visits to research laboratories to deepen the knowledge of the characterization techniques addressed during the theoretical lessons. In particular we will discuss X-ray diffraction techniques (Debye-Scherrer method, Bragg-Brentano automatic diffractometer), optical and electronic microscopy techniques with microprobe analysis, thermoanalytical (TA, DTA, TG) and calorimetric techniques (DSC , direct and indirect calorimetry). At the end of the course, the student will have to demonstrate the ability to analyze critically different experimental data concerning a "model" binary system such as the Mg-Cu, using the research material provided by the teacher and writing a report about the performed work.


Lectures (power point presentations, videos, discussion); classroom exercises in groups led by the teacher; visits to research laboratories in small groups with practical exercises guided by the teacher.

Class schedule

The timetable for this course is available here: Portale EasyAcademy



The exam consists of a written test and an oral exam. Only by obtaining a sufficient score (≥18 / 30) for the written test, student will be admitted to the oral exam. Both tests will compete for the final grade, which in any case must reach sufficiency. The judgment about the report will be considered as well for the final grade.

During the oral exam the knowledge of the topics covered during the lessons, the practical exercises will be verified and, if necessary, particular critical issues relating to the written test will be discussed.


The student's preparation will be ascertained not only with respect to the knowledge of the topics addressed during lectures, exercises in the classroom and in the research laboratories but also with respect to the skills acquired (e.g. reading of real state diagrams, critical analysis of experimental results) .

The written test will last 90 minutes and will consist of both open answers and multiple choice questions. The oral exam is always conducted by two tenured teachers with exams experience in the discipline and lasts at least 30 minutes.

Through the methods described, the exam board is able to verify with high accuracy the achievement of the educational objectives of the teaching.
