Objective
The objective is to study in depth the crystals chemistry of the interfaces in order to optimize the parameters which are important for specific applications.
This programme investigates interfacial segregation in oxide ceramics and evaluates the effect of this segregation on processing, reactivity and final properties. The project has studied in depth the crystal chemistry of the interfaces and the effect of segration on defect structure of the interface layer.
The most important conclusions are as follows:
oxygen activity in the gas phase results not only in changes of oxide nonstoichiometry and related defect concentration, but also in change of the mobility of electron carriers;
extensive experimental data has been provided on the application of the secondary ion mass spectrometry (SIMS) method in studies of ionic solids such as chromium doped cobalt oxide;
substantial changes have been found in structure and composition of boundary layers during cooling, which may be useful in engineering desired ceramic properties;
impurities may have substantial effects on interface composition.
New data has been achieved for compounds of commercial importance such as barium titanium oxide and strontium titanium oxide. Several bits of evidence suggest that segregation of defects may result in the formation of low dimensional interface structures of outstanding properties.
This programme will investigate interfacial segregation on processing, reactivity and final properties.
The project involves a review of the present state of knowledge of defect chemistry for near-surface and grain boundary regions, the derivation of a theory of segregation and the determination of the effect of segregation on the heterogeneous kinetics. The construction of a prototype surface sensitive equipment will allow in situ surface characterization of materials at elevated temperatures and under controlled gas atmospheres. The emphasis will focus on model oxide systems such as NiO, CoO, TiO2 and perovskites such as BaTiO3 and their solid solutions.
