Book Description
Vol 2A: Basic TechnologiesHandbook of Crystal Growth, Second Edition Volume IIA (Basic Technologies) presents basic growth technologies and modern crystal cutting methods. Particularly, the methodical fundamentals and development of technology in the field of bulk crystallization on both industrial and research scales are explored. After an introductory chapter on the formation of minerals, ruling historically the basic crystal formation parameters, advanced basic technologies from melt, solution, and vapour being applied for research and production of the today most important materials, like silicon, semiconductor compounds and oxides are presented in detail. The interdisciplinary and general importance of crystal growth for human live are illustrated.Vol 2B: Growth Mechanisms and DynamicsHandbook of Crystal Growth, Second Edition Volume IIB (Growth Mechanisms and Dynamics) deals with characteristic mechanisms and dynamics accompanying each bulk crystal growth method discussed in Volume IIA. Before the atoms or molecules pass over from a position in the fluid medium (gas, melt or solution) to their place in the crystalline face they must be transported in the fluid over macroscopic distances by diffusion, buoyancy-driven convection, surface-tension-driven convection, and forced convection (rotation, acceleration, vibration, magnetic mixing). Further, the heat of fusion and the part carried by the species on their way to the crystal by conductive and convective transport must be dissipated in the solid phase by well-organized thermal conduction and radiation to maintain a stable propagating interface. Additionally, segregation and capillary phenomena play a decisional role for chemical composition and crystal shaping, respectively. Today, the increase of high-quality crystal yield, its size enlargement and reproducibility are imperative conditions to match the strong economy.Volume 2A - Presents the status and future of Czochralski and float zone growth of dislocation-free silicon - Examines directional solidification of silicon ingots for photovoltaics, vertical gradient freeze of GaAs, CdTe for HF electronics and IR imaging as well as antiferromagnetic compounds and super alloys for turbine blades - Focuses on growth of dielectric and conducting oxide crystals for lasers and non-linear optics - Topics on hydrothermal, flux and vapour phase growth of III-nitrides, silicon carbide and diamond are explored Volume 2B - Explores capillarity control of the crystal shape at the growth from the melt - Highlights modeling of heat and mass transport dynamics - Discusses control of convective melt processes by magnetic fields and vibration measures - Includes imperative information on the segregation phenomenon and validation of compositional homogeneity - Examines crystal defect generation mechanisms and their controllability - Illustrates proper automation modes for ensuring constant crystal growth process - Exhibits fundamentals of solution growth, gel growth of protein crystals, growth of superconductor materials and mass crystallization for food and pharmaceutical industries

Book Description
Crystals are the unacknowledged pillars of modern technology. The modern technological developments depend greatly on the availability of suitable single crystals, whether it is for lasers, semiconductors, magnetic devices, optical devices, superconductors, telecommunication, etc. In spite of great technological advancements in the recent years, we are still in the early stage with respect to the growth of several important crystals such as diamond, silicon carbide, PZT, gallium nitride, and so on. Unless the science of growing these crystals is understood precisely, it is impossible to grow them as large single crystals to be applied in modern industry. This book deals with almost all the modern crystal growth techniques that have been adopted, including appropriate case studies. Since there has been no other book published to cover the subject after the Handbook of Crystal Growth, Eds. DTJ Hurle, published during 1993-1995, this book will fill the existing gap for its readers. The book begins with "Growth Histories of Mineral Crystals" by the most senior expert in this field, Professor Ichiro Sunagawa. The next chapter reviews recent developments in the theory of crystal growth, which is equally important before moving on to actual techniques. After the first two fundamental chapters, the book covers other topics like the recent progress in quartz growth, diamond growth, silicon carbide single crystals, PZT crystals, nonlinear optical crystals, solid state laser crystals, gemstones, high melting oxides like lithium niobates, hydroxyapatite, GaAs by molecular beam epitaxy, superconducting crystals, morphology control, and more. For the first time, the crystal growth modeling has been discussed in detail with reference to PZT and SiC crystals.

Book Description
This book examines and summarizes data on more than 40,000 diamonds from deposits in Russia’s diamondiferous Arkhangelsk province. The geological data of diamond deposits includes the geological setting, ore body morphology and mineral composition. Investigation techniques employed include: Color Cathode Luminescence, Fourier Transform Infrared Spectroscopy, Electron Paramagnetic Resonance, Raman Spectroscopy, and Carbon Isotopy. The book provides a full description of the diamond morphology. The problems of a potential (mantle) diamond grade for deposits are considered, depending on the physical and chemical conditions involved in the genesis and growth of diamond crystals. Further, there can be a significant impact on the productivity of bodies and the properties of diamonds during post-crystallization metasomatic processes. In this book, the authors propose a diamond crystallization model for changes in diamond crystals within mantle metasomatic transformations, and identify the factors affecting the growth and dissolution of diamonds in the mantle. In addition, they describe the complex evolution of kimberlite from the mantle up to the Earth’s surface. All of these factors affect the quality and quantity of diamonds in a particular diamond deposit, providing the basis for identifying optimal technological mining processes.

Book Description
Diamond is the record-setter in many mineralogical properties such as hardness, diffusivity, thermal conductivity, purity, and covalency of bonding. Similarly, diamond, as the premier gemstone of the mantle holds primacy for geological features such as age and depth of origin. Diamond was among the first crystalline structures to be solved by X-ray diffraction and the first materials measured for their Raman spectrum. At more than 80 billion USD in yearly commercial value, diamond sets the record for the most traded, valuable mineral on the planet. Despite its chemical simplicity, diamond has been the object of more research effort, and had more scientific and popular press pages written about it, than any other mineral.

Book Description
This book sheds valuable new light on the genetic mineralogy of lower-mantle diamonds and syngenetic minerals. It presents groundbreaking experimental results revealing the melting relations of ultrabasic and basic associations and a physicochemical peritectic mechanism of their evolution. The experimental investigations included here reveal the key multicomponent, multiphase oxide-silicate-carbonate-carbon parental media for lower-mantle diamonds and syngenetic minerals. Consequently, readers will find extensive information on the diamond-parental oxide-silicate-carbonate-carbon melts-solutions that supplement the general features of lower-mantle diamond genesis and the most efficient ultrabasic-basic evolution. The experimental results on physicochemical aspects, combined with analytical mineralogy data, make it possible to create a generalized composition diagram of the diamond-parental melts-solutions, there by completing the mantle-carbonatite concept for the genesis of lower-mantle diamonds and syngenetic minerals. This book addresses the needs of all researchers studying the Earth’s deepest structure, super-deep mineral formation including diamonds, and magmatic evolution.
