Course detail
Synthesis of Nonmetallic Materials
FSI-WCH Acad. year: 2021/2022 Winter semester
The course is focused on the synthesis of non-metallic materials-polymers and ceramic powders, including the behaviour of ceramic colloidal particles in liquid media. The aim of the course is to provide students of material engineering with fundamental physical and chemical information about synthesis of non-metallic materials and their precursors, which are important for understanding the relations between the structure of materials end their (physical) chemical reactivity.

Learning outcomes of the course unit
Students will be able to use the acquired knowledge in the following master studies of material engineering and to the solution of appropriate problems of industrial practice.
Prerequisites
The knowledge of inorganic, organic and physical chemistry on the secondary school level or basic course of chemistry of mechanical engineering is assumed.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical laboratory work.
Assesment methods and criteria linked to learning outcomes
Course-unit credit requirements: attendance at seminars and fulfilment of assignments. Examination verifies the knowledge of the theory and its applications to solving practical problems. The exam is oral with a written preparation time.
Aims
The aim of the course is to provide the students of material engineering fundamental physical and chemical information about synthesis of non-metallic materials and their precursors, which are important for understanding the relations between the structure of materials end their (physical) chemical reactivity.
Specification of controlled education, way of implementation and compensation for absences
Attendance at seminars and fulfilment of assignments is required. In case students do not meet these conditions they can be given additional assignments.
