Crystal Structures of Metals and Ceramics

This lecture covers the crystal structure characteristics of metals, including simple cubic, body-centered cubic, face-centered cubic, and hexagonal close-packed structures. It also discusses the crystalline states of metals, alloys, and ceramics, as well as imperfections in solids and the coordination numbers in ceramics. The instructor explains the polymorphism of materials like titanium and carbon, the structure of alloys, and the interstitial sites in crystal structures. Additionally, the lecture delves into the crystal structures of ceramics, the role of silica and silicates, and the amorphous materials like glasses and metallic glasses.
