      The goalIntroduction to the basic principles of the science of sintering, the impact of the process of synthesis on structure and properties of sintered materials. Acquiring engineering knowledge required for independent performing engineering calculations of parameters for obtaining various types of powders and sinters, introduction of experimental techniques and independent research, control and governance of processes in sinter metallurgy, further training in the field of powder metallurgy, design, technology and environmental protection.
      The outcomeCourse provides necessary knowledge for understanding process of powder metallurgy, enables students that with minimal research, through modeling and simulation of the sintering process define new technologies and methods for obtaining material with predicted properties. Providing engineering knowledge necessary for further teaching and experimental activities in a field of obtaining special powders and composites, powder recycling and environmental protection.
