Learning outcomes

Knowledge of new inorganic chemical synthesis methods. The introduction is based on both principal and practical approaches. Knowledge of tailored special structures and properties. b) Abilities The students possess knowledges after the completion of this course, by means of attainments they are able to synthesize functional materials with new structures and properties, macroscopic and supramolecular characterization of material systems. c) Attitude The students have possibility to become opened for acquirement of new ideas, construction of material systems by means of the acquired abilities in their work. The students can work environmentally friendly, try to develop new methods with low environmental loading. The students may be capable for good professional collaboration due to education at the university. d) Autonomy and responsibility The education at the university helps in the invention of independent ideas, cleaning professional questions, and making meaningful compilations, and in observance of work safety regulations.

Course content

One of the main aims of sol-gel technique application is the replacement of the traditional melt-quenching technology. The sol-gel technique uses relatively low temperatures. By sol-gel method can synthesize systems, which cannot be prepared by traditional melting process. The other important new aim is controlling and tailoring the material structures even in the nano-scale or molecular range. Development of new unique material properties by means of formation of new structures and preparation routes. Sol-gel method is a versatile technique: it produces coatings and thin films, monoliths, composites, porous membranes, powders and fibers. Over these types of materials, the sol-gel procedure is a unique preparation technique for hybrid systems. The topic of lectures covers the gelation techniques, the chemical reactions, and various drying techniques of silicate, aluminate, titanate, zirconium-, and boron-containing systems.

Assessment method

oral or written exam (K5)
