Morphology of Crystals by Ichiro Sunagawa Pdf

The molecular mechanisms underlying the fact that a crystal can take a variety of external forms is something we have come to understand only in the last few decades. This is due to recent developments in theoretical and experimental investigations of crystal growth mechanisms. Morphology of Crystals is divided into three separately available volumes. Part A contains chapters on roughening transition; equilibrium form; step pattern theory; modern PBC; and surface microtopography. This part provides essentially theoretical treatments of the problem, particularly the solid-liquid interface. Part B contains chapters on ultra-fine particles; minerals; transition from polyhedral to dendrite; theory of dendrite; and snow crystals. All chapters are written by world leaders in their respective areas, and some can be seen as representing the essence of a life's work. This is the first English-language work which covers all aspects of the morphology of crystals - a topic which has attracted top scientific minds for centuries. As such, it is indispensable for anyone seeking an answer to a question relating to this fascinating problem: mineralogists, petrologists, crystallographers, materials scientists, workers in solid-state physics and chemistry, etc. In Parts A: Fundamentals and B: Fine Particles, Minerals and Snow equilibrium and kinetic properties of crystals are generally approached from an `atomistic' point of view. In contrast, Part C: The Geometry of Crystal Growth follows the alternative and complementary `geometrical' description, where bulk phases are considered as continuous media and their interfaces as mathematical surfaces with orientation-dependent properties. Equations of motion for a crystal surface are expressed in terms of vector and tensor operators working on surface free energy and growth rate, both expressed as functions of surface orientation and driving force, or `affinity' for growth. This approach emphasizes the interrelation between equilibrium and kinetic behavior. Part 1 establishes the theoretical framework. Part 2 gives a construction toolbox for explicit (analytic) functions. An extra chapter is devoted to experimental techniques for measuring such functions: a new approach to sphere growth experiments. The emphasis throughout is on principles and new concepts. Audience: Advanced readers familiar with traditional aspects of crystal growth theory. Can be used as the basis for an advanced course, provided supplementation is provided in the areas of atomistic models of the advancing surface, diffusion fields, etc.

Structure and Bonding in crystals by Michael O'Keeffe Pdf

Structure and Bonding in Crystals presents a new understanding of the older topics such as bond length, bond strength, and ionic radii. These concepts have been used by geochemists and geophysicists to systematize and predict phase transitions at high pressure. The final group of chapters deals with the problems of classifying complex solids and with systematic descriptions of the relationships between their structures. This book comprises 13 chapters, with the first presenting a historical perspective by Linus Pauling. The following chapters then go on to discuss quantum theory and crystal chemistry; pseudopotentials and crystal structure; quantum-defect orbital radii and the structural chemistry of simple solids; and a pseudopotential viewpoint of the electronic and structural properties of crystals. Other chapters cover elementary quantitative theory of chemical bonding; the role and significance of empirical and semiempirical correlations; theoretical probes of bonding in the disiloxy group; a comparison of experimental and theoretical bond length and angle variations; the role of nonbonded forces in crystals; molecules within infinite solids; charge density distributions; and some aspects of the ionic model of crystals. This book will be of interest to practitioners in the fields of chemistry, physics, and geology.

Crystals by Ichiro Sunagawa Pdf

How do crystals nucleate and grow? Why and how do crystals form such a wide variety of morphologies, from polyhedral to dendritic and spherulitic forms? These are questions that have been posed since the seventeenth century, and are still of vital importance today both for modern technology, and to understand the Earth's interior and the formation of minerals by living organisms. In this book, Ichiro Sunagawa sets out clearly the atomic processes behind crystal growth, and describes case studies of complex systems from diamond, calcite and pyrite, to crystals formed through biomineralization, such as the aragonite of shells, and apatite of teeth. Essential reading for advanced graduates and researchers in mineralogy and materials science.

Crystallography by Walter Borchardt-Ott Pdf

As a self-study guide, course primer or teaching aid, Bor- chardt-Ott's Crystallography is the perfect textbook for students and teachers alike. In fact, it can be used by chemists, mineralogists, physicists and geologists. Based on the author's more than 20 years of teaching experience, the book has numerous line drawings designed especially for the text and a large number of exercises - with solutions - at the end of each chapter. The fourth edition of the original German text has been translated into English for an international readership. The heart of the book is firmly fixed in geometrical crystallography. It is from the concept of the space lattice that symmetry operations, Bravais lattices, space groups and point groups are all developed. Molecular symmetry and crystal formsare treated. Much emphasis is placed on the correspondence between point groups and space groups. The sections on crystal chemistry and X-ray diffraction are intended as an introduction to these fields.

Symmetry Relationships between Crystal Structures by Ulrich Müller Pdf

In crystal chemistry and crystal physics, the relations between the symmetry groups (space groups) of crystalline solids are of special importance. Part 1 of this book presents the necessary mathematical foundations and tools: the fundamentals of crystallography with special emphasis on symmetry, the theory of the crystallographic groups, and the formalisms of the needed crystallographic computations. Part 2 gives an insight into applications to problems in crystal chemistry. With the aid of numerous examples, it is shown how crystallographic group theory can be used to make evident relationships between crystal structures, to set up a systematic order in the huge amount of known crystal structures, to predict crystal structures, to analyse phase transitions and topotactic reactions in the solid state, to understand the formation of domains and twins in crystals, and to avoid errors in crystal structure determinations. A broad range of end-of-chapter exercises offers the possibility to apply the learned material. Worked-out solutions to the exercises can be found at the end of the book.

Structure and Bonding in crystals by Alexandra Nsvrotsky Pdf

Structure and Bonding in Crystals, Volume II discusses the factors determining crystal structure. This book examines the principles of structure and bonding in complex solids. Divided into 13 parts, this volume begins with an overview of the development of atomic pseudopotentials and the discovery that they could be applied directly to atoms in crystals. This book then provides an understanding of other relevant topics, including ionic radii, bond strength, and bond length. Other chapters focus on the problems of classifying complex solids and describe the relationship between their structures. This text also describes the alloy structure to help know how compounds react or transform. This book further explores the geometrical relationships between different structure types in crystals. The final chapter deals with the contribution of Mooser and Pearson in the study of energy-band theory and chemical bonding. Solid-state physicists and chemists, geophysicists, metallurgists, and ceramists will find this book extremely useful.

Classic and Advanced Ceramics by Robert B. Heimann Pdf

Based on the author's lectures to graduate students of geosciences, physics, chemistry and materials science, this didactic handbook covers basic aspects of ceramics such as composition and structure as well as such advanced topics as achieving specific functionalities by choosing the right materials. The focus lies on the thermal transformation processes of natural raw materials to arrive at traditional structural ceramics and on the general physical principles of advanced functional ceramics. The book thus provides practice-oriented information to readers in research, development and engineering on how to understand, make and improve ceramics and derived products, while also serving as a rapid reference for the practitioner. The choice of topics and style of presentation make it equally useful for chemists, materials scientists, engineers and mineralogists.
