In the course, students are introduced to basics of fabrication of ceramic powders and their characterization, as well as to modern sintering methods. The factors influencing sintering process are addressed and discussed. Shaping of green body by uniaxial and isostatic pressing and the use of pressing aids. Analysis of chemical equilibria and diffusion processes during solid and liquid phase sintering. Particular attention is placed on control of microstructure during sintering and correlation with the properties (mechanical, thermal, electrical, magnetic, etc.) of bulk sintered ceramics. Advantages and disadvantages of various sintering techniques are considered from the practical, technical and economic point of view.
The course acquires knowledge of sintering theory and modern sintering methods currently used in engineering and scientific practice. After the course the student should be able to:
• describe the interactions between the parameters for the manufacturing of a homogeneous, high density green part
• describe the driving forces and mechanisms of material transport that govern the different stages of sintering of an aggregate of solid particles
• characterize the effect of porosity and density on the properties (microstructural, mechanical, thermal, electrical, magnetic, etc.) of bulk sintered ceramics
• specify and classify the different methods of sintering, as well as their advantages and limitations |
