Course content
|
Properties of powdery materials, especially pigments and fillers (their chemical, structural, physical and technological properties). Colour properties of inorganic pigments (reasons of colour, objective methods of colour measurements - systems XYZ, xyz, CIE L*a*b*, standardization of measurement conditions, calculation of colour difference and its meaning) Optical properties of pigments (hiding power and its connection with refractive index and particle size, Kubelka-Munk theory, tinting strength, lightfastness and weather resistance). Classification of inorganic pigments and technology. Basic principles of coloured high-temperature stable pigments preparation (thermodynamic and kinetic factors) and their survey. Other groups of special inorganic pigments - nacreous and metallic pigments, luminescent pigments (their optical principles and preparation).

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.
