Course detail

Synthesis of Nonmetallic Materials

FSI-WCHAcad. year: 2022/2023

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.
