Colloidal processing of ceramic nanoparticles
The subject of the PhD study is focused on shaping and consolidation of nanoceramic oxide particles. The main task of the student will contain a study of bulk colloidal ceramics processing using ceramic particles with size below 100 nm via colloidal shaping methods. The research will concern primarily with methods of direct consolidation of ceramic particles. A common difficulty of all these methods lies in the preparation of a stable concentrated suspension of nanoparticles with appropriate viscosity. The solution of the problem assumes understanding and utilization of colloidal chemistry and rheology of ceramic suspensions.
Machinable ceramics for 3D milling
The topic of this PhD study is a development of processing methods for a unique manufacturing of ceramic prototypes and small series of complex ceramic parts using 3D milling. The dissertation is focused on research into semiproducts (blanks) of advanced ceramics for 3D milling based on zirconia, alumina, calcium phosphates and other materials for dental and structural applications and prospectively even for customized complex-shaped surgical implants. The blanks will be prepared for both dense ceramic parts and bodies from a ceramic foam. For preparation of large and complex parts shaped machinable blanks will be developed that can ensure reliable and economical production of such parts. The blanks will be processed by CAD/CAM methods utilizing CNC milling.
3D printing of ceramic structures by LCM Method
The PhD work will be concerned with manufacturing of complex ceramic parts with internal structure using the LCM method (Lithography-based Ceramic Manufacturing). The research will be focused on investigation of ceramic suspensions for the LCM method and on correlation between the processing conditions of LCM method and the properties of the final ceramic parts. The research will be aimed at applications in medicine. The internal structure of calcium phosphate bioscaffolds for bone regeneration will be optimized with respect to modification of ceramic skeleton with inorganic as well as organic biopolymers.
Thin flexible ceramic sheets for electrotechnical applications
The topic of the dissertation thesis focuses on research into flexible self-supporting ceramic foils with a thickness ranging from 0.05 to 1 mm. The research will be concern with the preparation of ceramic foils and with mechanical, electrical, or optical properties of such foils. The basic task will be the development of unique methods for the preparation of ceramic foils from nanoparticulate suspensions. The research will be aimed at electrotechnical applications that utilize ceramic foils as flexible dielectric substrates or piezoceramic energy harvesters.
Development of piezoelectric lead-free ceramics for energy harvesting
Recently, energy harvesting based on piezoelectric ceramics has attracted wide attention as an electric energy source for low-power electronics. Due to environmental aspects the commonly available piezoceramic generators based on PZT (Pb-Zr-Ti-O) must be replaced by lead-free materials. BCZT (Ba-Ca-Zr-Ti-O) a BT (BiFeO3) are very promising lead-free piezoelectric ceramic materials for this application. The work will be, therefore, focused on the development and study of these unleaded materials and their controlled doping for the purpose of efficient electric energy harvesting. The student will develop processes for preparation of piezoceramic and composite piezoceramic tapes for application in energy harvesters. The efficiency of the new materials in the energy harvesting will be evaluated. Internship at the University of Oulu is planned during the study.
