1. Synthesis and characterisation of high tech ceramic materials with important technological applications in industry and electronics. This research group is predominantly active in the synthesis and characterisation of high tech ceramic oxides with promising improved mechanical and electrical properties. The group currently consists of 8 Ph.D. students (Kristof Van Werde, Dirk Mondelaers, Daniël Nelis, An Hardy, John Pagnaer, Elke Geuzens, Dirk Van Genechten, Annick Storms) and 4 postdoctoral researchers (Prof. dr. Lucien Van Poucke, Prof. dr. Jules Mullens, Dr. Marlies Van Bael, Dr. Heidi Van den Rul). The expertise of the group is recently acknowledged by the accession of the GBOU-project ┐Preparation of nanomodified multimetal oxides: aqueous solution synthesis and processing└ including a fund of 1.66 million ı. The project endures till the end of the year 2005 in an intensive collaboration with the Silicon Technology and Device Integration section of IMEC, with the MTM department of the KULeuven and with the Material Technology and Ceramic Processing section of VITO. Nine enterprises, Agfa-Gevaert, Agio, BC Components, Bekaert Advanced Materials, Heraeus Electro Nite, Philips Research Eindhoven, Sonitron, UCB Chemicals en Umicore, participate in the consumerscommission which was specifically created for this project, in terms of the realisation of maximal industrial applications and the valorisation of the obtained knowledge. Special attention will go to the synthesis of nanomaterials (dimension from 1 to 100nm) using environmentfriendly aqueous methods. This concerns oxides from the type perovskite like PZT Pb(ZrxTi1-x)O3, SBT SrBi2(Ta1-xNbx)2O9, BLT Bi4-xLaxTi3O12, 0.75 Pb(Zn1/3,Nb2/3)O3 ├ 0.25 BaTiO3 (PZN-BT), but also systems like ZnO, Al2O3 en ZrO2. These types of high tech ceramics, consisting of films, nanoparticles and nanocomposites are not restricted to the application as structural ceramics (mechanical properties) but also as functional ceramics because of their electrical properties, making them strategically important concerning future electronic developments. Direct applications are solar cells, fuel cells, FERAMs (non-volatile memory resistent to power-failure), MEMs (Micro Electro Mechanical systems) en biosensors. The research group has got access to electronmicroscopical techniques like SEM and (cryo)TEM and exposes various instrumental techniques in the field of structure determination (FT-IR), Raman, XRD), elemental analysis (AAS, ICP-AES), thermal analysis (DSC, STA, high-resolution TGA, TGA coupled on-line with MS and FT-IR) required for synthesis and characterisation. By focussing synthesis predominantly on nanomaterials, the group is involved in recent developments in industry in the search of innovative properties en applications.
