This book provides beginning graduate or senior-level undergraduate students in materials disciplines with a primer of the fundamental and quantitative ideas on kinetic processes in solid materials. Kinetics is concerned with the rate of change of the state of existence of a material system under thermodynamic driving forces. Kinetic processes in materials typically involve chemical reactions and solid state diffusion in parallel or in tandem. Thus, mathematics of diffusion in continuum is first dealt with in some depth, followed by the atomic theory of diffusion and a brief review of chemical reaction kinetics. Chemical diffusion in metals and ionic solids, diffusion-controlled kinetics of phase transformations, and kinetics of gas-solid reactions are examined. Through this course of learning, a student will become able to predict quantitatively how fast a kinetic process takes place, to understand the inner workings of the process, and to design the optimal process of material state change.

• Provides students with the tools to predict quantitatively how fast a kinetic process takes place and solve other diffusion related problems;
• Learns fundamental and quantitative ideas on kinetic processes in solid materials;
• Examines chemical diffusion in metals and ionic solids, diffusion-controlled kinetics of phase transformations, and kinetics of gas-solid reactions, among others;

• Contains end-of chapter exercise problems to help reinforce students' grasp of the concepts presented within each chapter.

  Prof. Han-Ill Yoo is the President (2017-2019) of the International Society for Solid State Ionics. He received his Ph.D in Ceramics from the Department of Materials Science and Engineering, Massachusetts Institute of Technology, USA, in 1984. He had since affiliated with the faculty of the Department of Materials Science and Engineering, Seoul National University until his retirement in 2017, and is now with Daegu Gyeongbuk Institute of Science and Technology(DGIST) as Invited Chair Professor. He has been teaching Thermodynamics and Kinetics along with his lifelong research in defect chemistry and mass/charge transport properties of ceramics. In the course of this research, he discovered a ceramic material with zero electronic thermopower, established the experimental methods to determine all the mass and charge transport properties in terms of the Onsager transport coefficients, and experimentally demonstrated the Onsager reciprocity between ionic and electronic flows in mixed ionic electronic conductors. Recently, he has been conducting research into the nonisothermal mass/charge transport properties of ceramics. He was awarded the Alexander von Humboldt Research Award in 2004 and elected to Fellow at College of Engineering, The University of Tokyo in 2009.
