Models Manufacturing of Crystal Systems: An Introduction to Ceramic Materials

Abstract

It is presented a teaching methodology that uses models to better understanding and visualization of crystal systems, considering the large number of students with limited vision spatial perception. The understanding of the relationship between the structure of materials with their properties is essential for engineering students in which it’s possible to relate mechanical properties through knowledge of the crystalline structure of the material, such as machining, heat treatment, mechanical forming processes, etc. The parameter identification of: number of atoms, coordination number, atomic packing factor and density is emphasized in the crystalline systems. Students first study the structure of the crystalline solid and the main crystal systems, key issues for further understanding of the remaining content. Knowing the structure of crystalline solids and understanding its applicability in engineering, makes all the difference to motivate students during the course. With the inclusion of this methodology there has been a better understanding of the concepts related to crystalline systems, as the students build their own structures with the most suitable material chosen by them.
