Focusing on the physical properties of diamond and sapphire, this monograph provides readers with essential details on crystal structure and growth, mechanical properties, thermal properties, optical properties, light scattering of diamond and sapphire crystals, and sapphire lasers. Various physical properties are comprehensively discussed: Mechanical properties include hardness, tensile strength, compressive strength, and Young’s modulus. Thermal properties include thermal expansion, specific heat, and thermal conductivity. Optical properties of diamond and sapphire include transmission, refractive index, and absorption. Light scattering includes Raman scattering and Brillouin scattering. Sapphire lasers include chromium-doped and titanium-doped lasers. Aimed at researchers and industry professionals working in materials science, physics, electrical engineering, and related fields, this monograph is the first to concentrate solely on physical properties of these increasingly important materials.

Ceramic Materials: Science and Engineering is an up-to-date treatment of ceramic science, engineering, and applications in a single, comprehensive text. Building on a foundation of crystal structures, phase equilibria, defects, and the mechanical properties of ceramic materials, students are shown how these materials are processed for a wide diversity of applications in today's society. Concepts such as how and why ions move, how ceramics interact with light and magnetic fields, and how they respond to temperature changes are discussed in the context of their applications. References to the art and history of ceramics are included throughout the text, and a chapter is devoted to ceramics as gemstones. This course-tested text now includes expanded chapters on the role of ceramics in industry and their impact on the environment as well as a chapter devoted to applications of ceramic materials in clean energy technologies. Also new are expanded sets of text-specific homework problems and other resources for instructors. The revised and updated Second Edition is further enhanced with color illustrations throughout the text.
