Micro/nano-structured ceramics & coatings
The precursor-based approach to advanced ceramics is an intelligent way of producing ceramics of complex compositions where design of ceramics can be done at an atomistic/molecular scale. Through modulating the chemical configuration of a precursor molecules, the physicochemical properties of the precursors such as volatility or thermal stability, can be controlled to produce amorphous/nanocrystalline ceramics in various forms (nanopowders, fibres, coatings, thin films). It is also possible to adapt to the needs of deposition techniques such as chemical vapor deposition. It is proposed to produce a variety of structural and functional coatings in this domain using various deposition techniques such as atomic layer deposition (ALD), chemical vapor deposition (CVD) and powder aerosol deposition (PAD). The scientific challenges are immense, with respect to stability of coatings, thermodynamics of the phases, interfacial chemistry and mechanics.
