Learning activities and teaching methods
Monologic (reading, lecture, briefing)
Learning outcomes
Students make the acquaintance of problems concerning inorganic pigments, their properties and production including theoretical principles of their synthesis.
Students receive information about effect of different methods of pigment preparation, possibilities of increase of reactivity of raw materials and mechanisms used for their synthesis. The students can characterize physical-chemical, application and technology properties of inorganic pigments and discuss their influence on quality of pigments.
