Ceramics are a business card of China, and porcelain is even known as China's fifth largest invention, and its appearance has had a significant impact on human civilization. At present, with the rapid development of science and technology, ceramic materials have also become a hot spot in competition in the field of high-tech. However, compared with the complete theoretical system formed by the microstructure of metal materials, ceramic materials pale in comparison.
In response to this gap, the author of "Theory of Microstructure Formation of Ceramic Materials" summarized and summarized the basic concepts, mathematical models and characteristic laws involved in the formation of microstructure during ceramic materials sintering and liquid-solid transformation from a unique perspective.
Ceramic Materials
Currently, the application of artificial intelligence in materials is becoming a hot spot in the big data economy. The future material science will be built on the basis of data and artificial intelligence. Based on a large amount of data, machine learning and data mining technology will be used to establish a connection between components-structure-process-performance faster, more accurately and more efficiently. Therefore, the need for quantitative calculations in materials research is also particularly urgent, and the publication of this book is just at the right time.
This book focuses on two important process processes in the preparation of ceramic materials - sintering and solidification. It systematically explains the basic concepts, mathematical models and characteristic laws involved in the formation of microstructures, and explains in detail the physical essence, accompanying phenomena and influencing factors of the tissue formation process. It aims to help readers understand the theoretical knowledge involved in the formation of microstructures of ceramic materials.
Academician of the Chinese Academy of Engineering, former president of Harbin Institute of Technology, and expert in ceramic materials Professor Zhou Yu wrote the preface to this book.
Part 1 is ceramic sintering theory (Chapter 1 to 3) , starting from three aspects: solid phase sintering (Chapter 1), liquid phase sintering (Chapter 2) and special sintering (Chapter 3), and telling the theoretical model and microstructure evolution of ceramic materials during the sintering process. This section summarizes the development history of sintering theory, and combines the latest research progress in ceramic sintering to discuss the densification process and microstructure evolution of materials under different sintering methods. The solid phase sintering chapter includes: sintering thermodynamics , sintering model, densification kinetics, and grain growth. The liquid phase sintering chapter includes: liquid phase sintering densification process, liquid phase sintering conditions and influencing factors, and liquid phase sintering mechanism. Special sintering chapters include: electric field-assisted sintering, magnetic field-assisted sintering, discharge plasma sintering and microwave sintering.
Part 2 is the theory of solidification structure formation of eutectic ceramics (Chapters 4-6) , which introduces the microstructure evolution and control of eutectic ceramics during solidification, including the microstructure characteristics of eutectic ceramics (Chapter 4), eutectic solidification behavior and growth model (Chapter 5), liquid-solid interface stability and dendrites growth (Chapter 6). This part of the content takes the quantitative model as the main line, from the migration of solute atoms, interface structure, interface stability and solute redistribution at the solid-liquid interface, from cell and dendritic growth to eutectic growth and rapid solidification tissue formation, it systematically describes the general rules of eutectic solidification structure formation, integrates the solidification theory into a coherent system, and uses specific experimental results combined with rich illustrations to give readers a visual display.
This book contains many formulas and pictures. The author sorted out the background, physical model, evolution process and application scope of these formulas. This is a meditation practice process that requires refining the details and repeated deductions.
This book opens a window for readers to peek into the world of ceramics.

Content Introduction
Advanced ceramics are new inorganic non-metallic materials, also known as fine ceramics, high-performance ceramics or high-tech ceramics, and are widely used in aerospace, machinery, metallurgy, chemical and other industries. This book mainly includes two parts: ceramic sintering theory and eutectic ceramic solidification structure formation theory, with a total of 6 chapters.The first part mainly talks about the theoretical model and microstructure formation rules during the sintering process from three aspects: solid-phase sintering, liquid-phase sintering and special sintering; the second part talks about the evolution of microstructure and its formation mechanism during the sintering process from the three aspects: solid-phase sintering, liquid-phase sintering and special sintering; the second part takes microstructure, solid-set behavior, growth model, etc. as the entry point, and talks about the evolution of microstructure and its formation mechanism during the solid-down process.
This book can be used as a reference for technical personnel engaged in advanced ceramic research, development and production in the fields of national defense industry, aircraft thermal protection, electronic information, biomedicine, etc., and can also be used as a professional reference for senior undergraduates and graduate students in engineering majors such as materials processing engineering, aerospace, and mechanical engineering in universities and research institutes.
