Abstract
A modern approach to research in the field of structural ceramics comes from an understanding of the basic principles of the interactions between particles in a variety of media and together with a knowledge of the state-of-the-art and the development of new manufacturing techniques for ceramic materials from powders represents the cornerstone of the development of ceramic materials and products. The proposed research program will deal with the research and development of new and improved structural ceramic materials and products for use in technology and medicine, with a focus on contemporary and the development of new processing methods. The basic research will involve research on the relationships between the preparation, structure, composition and properties of ceramic materials and products as well as the physical phenomena and chemical reactions important for the control of ceramic production technologies. We will explore possibilities for the synthesis of various ceramic coatings and the surface modification of ceramic particles and materials using nanoparticles. The research on the interactions between particles in different media will serve to improve the existing, and develop new methods for powder processing and shaping of engineering parts. We will use advanced methods for the densification of ceramic and composite materials that allow the preservation of grain sizes at the “nano” level, and of size-dependent unique material properties. We will also investigate the mechanisms and kinetics of the phase transformations of partially stabilized tetragonal zirconia under different conditions, which are still not satisfactorily explained. The applicative part of the research program will provide a verification of the functional properties and the potential use of materials developed in the context of basic research, prototyping and the development of pilot technologies. We will investigate the functionalization of ceramic materials using nanoparticles to produce conductive technical ceramics, self-healing materials and composite materials with improved mechanical properties; the synthesis of porous ceramic materials with a high specific surface area and/or tailored porosity useful for separation, catalysis, or sensors; the synthesis of a variety of ceramic coatings, such as those with a high specific surface area, intended for catalysis, improved adhesion or the bio-activation of surfaces and also dense ceramic coatings that can serve as a protection against the wear and oxidation or degradation in hostile environments. In the field of the research on materials for use in dentistry, we will focus on the aging and mechanical fatigue of ceramic dental prosthetic structures in simulated clinical conditions and in the oral cavity and begin with clinical testing of nanostructured coatings for the improved adhesion of dental cements.
Significance for science
With the proposed research program, basic and applicative knowledge from the field of material science that is one of the preferential areas in every industrially developed country, will be developed and expanded. The proposed research topics are actual and are included into the tendencies of the development of up-to-date structural and bioceramics all over the world: new materials with high strength, wear, corrosion and high-temperature resistance, on the one hand, and the development of new, alternative, cost-effective ceramic technologies on the other. The expected results will contribute to a better understanding of the properties of these materials and the mechanisms of their degradation. The study of the relations between the composition, structure and microstructure of such ceramic materials and their intrinsic and extrinsic properties will create the new knowledge needed for the design of new, multifunctional materials with improved efficiency and reliability. The research in the field of advanced ceramic processing and shaping technologies will contribute to a better understanding and mastering of the critical phases of the production processes. The results, however, are not useful only for engineering ceramics, but have a wider area of application. The principles established during the study of the dispersing of the ceramic particles in liquids are general and can be applied to all ceramic suspensions, including suspensions of nano-particles. The characteristic dominant populations of defects that originate from the processing of ceramics determine not only the mechanical but also other functional properties (electrical, magnetic, optical etc.). Also, the preparation of materials with hierarchically ordered pores and designed porosity by control of the particle interactions is not limited to ceramic materials.
Significance for the country
The applicative and development part of the program is aimed at the search for new possible applications of ceramic materials, into the development of new and/or cheaper materials with the desired properties and into the development of alternative, economical and environmentally friendly ceramic technologies. Part of this program is prepared in cooperation with experts from industry, in particular from spin-out company founded by our post-doc, that will also actively participate in its execution. It is expected that with this approach, part of the created knowledge will be transferred into practice. This will, on the one hand, contribute to an increase in the number of jobs and, on the other, to an increase in the competitiveness of Slovenian industry, which will by the introduction of high-tech products become internationally recognizable. This will enable easier cooperation in the frame of European development projects and more intensive collaboration with foreign industrial partners, the expansion of activities and the opening of new working places. The program group will also contribute to the technological development of Slovenia with the dissemination of knowledge in the form of counselling, literature surveys of potentially interesting areas, help in the solving of technological problems in production, cooperation in smaller or larger development projects and help with the introduction of new products and technologies, the specialization of the researchers from industry and lectures for technical staff, pedagogical activity in undergraduate and graduate studies and mentoring diplomas and doctoral thesis. With all this it will also contribute to the better education of students of natural and technical sciences. With the expansion of the research to the field of bioceramics a new, up-to-date problematic was introduced in Slovenian research area. It is expected that the closer cooperation of experts from the field of material science with experts from the field of medicine and bioceramics will enrich the educational programs and courses on technics as well as medicine. The active cooperation of industrial partners and end-users in the research of materials for high-tech and biomedicine applications will contribute to an increase of the technical level and an awareness of the public about the importance of this research for the environment and the society we live in. Nevertheless, the recognisability of the research group and its industrial partners contribute to the consolidation of national identity.
