The use of chemistry to design and synthesize materials with potentially useful physical attributes is known as materials chemistry. It is a subfield of materials science. It integrates concepts from physics and engineering. This field seeks to develop materials based on magnetic, structural, optical or catalytic properties. The processing, characterization and molecular-level understanding of these substances is also studied under this discipline. There are many applications of materials chemistry such as producing engineering ceramics, composite materials, polymers and metal alloys. This book provides comprehensive insights into the field of materials chemistry. It traces the progress of this field and highlights some of its key concepts. The extensive content of this book provides the readers with a thorough understanding of the subject.
