Synthesis Methods And Crystallization

New crystalline materials (organic, inorganic, hybrid) are promising for various applications, including electrical, piezoelectric, ferroelectric, magnetic, and catalytic processes. In addition, given their remarkable structural richness, these materials exhibit several interesting physical properties, such as ionic conduction, ion exchange, and others. Crystal growth, morphology, and grain size are factors influencing these physical properties. This book examines methods of synthesis of the most common crystalline materials and describes nucleation and crystal growth of various materials.

Preparative Methods in Solid State Chemistry deals with the preparative methods used in solid state chemistry and highlights the importance of the chemist's role in preparing materials of desired quality as well as obtaining materials according to the requirements of the user such as the physicist. Topics covered range from high-pressure techniques in preparative chemistry to methods of growing single crystals of high-melting-point oxides. This book is comprised of 14 chapters and begins with an overview of possibilities for high-pressure synthesis, as well as the methods used to obtain high pressures, including transmission by gaseous or liquid fluids or in the solid state. The method of shock waves is then considered both from the point of view of thermodynamics and thermoelasticity, along with the possibility of using superpressures for evidently revolutionary applications. Subsequent chapters focus on the synthesis of single crystals of refractory oxides either at high temperatures (essentially liquid-solid transformations) or at lower temperatures in the presence of a solvent or a chemical reagent. The production of single crystals by electrolytic reduction in molten salts is also described. Numerous examples of vapor transport reactions in a temperature gradient are presented. This monograph should be of interest to chemists and students of solid state chemistry.

In this volume, contributions covering the theoretical and practical aspects of multicomponent crystals provide a timely and contemporary overview of the state-of-the art of this vital aspect of crystal engineering/materials science. With a solid foundation in fundamentals, multi-component crystals can be formed, for example, to enhance pharmaceutical properties of drugs, for the specific control of optical responses to external stimuli and to assemble molecules to allow chemical reactions that are generally intractable following conventional methods.

This indispensable two-volume handbook covers everything on this hot research field. The first part deals with the synthesis, modification, characterization and application of catalytic active zeolites, while the second focuses on such reaction types as cracking, hydrocracking, isomerization, reforming and other industrially important topics. Edited by a highly experienced and internationally renowned team with chapters written by the "Who's Who" of zeolite research.

Multi-component crystalline systems or co-crystals have received tremendous attention from academia and industry alike in the past decade. Applications of co-crystals are varied and are likely to positively impact a wide range of industries dealing with molecular solids. Co-crystallization has been used to improve the properties and performance of materials from pharmaceuticals to energetic materials, as well as for separation of compounds. This book combines co-crystal applications of commercial and practical interest from diverse fields in to a single volume. It also examines effective structural design of co-crystals, and provides insights into practical synthesis and characterization techniques. Providing a useful resource for postgraduate students new to applied co-crystal research and crystal engineering, it will also be of interest to established researchers in academia or industry.

For much of the past 60 years, the U.S. research community dominated the discovery of new crystalline materials and the growth of large single crystals, placing the country at the forefront of fundamental advances in condensed-matter sciences and fueling the development of many of the new technologies at the core of U.S. economic growth. The opportunities offered by future developments in this field remain as promising as the achievements of the past. However, the past 20 years have seen a substantial deterioration in the United States' capability to pursue those opportunities at a time when several European and Asian countries have significantly increased investments in developing their own capacities in these areas. This book seeks both to set out the challenges and opportunities facing those who discover new crystalline materials and grow large crystals and to chart a way for the United States to reinvigorate its efforts and thereby return to a position of leadership in this field.

An excellent overview of the manifold aspects of modern crystal engineering. From design and preparation to spectroscopy and applications, this handbook both covers and evaluates all aspects of crystal engineering. Clearly structured, it provides an overview of the current status as seen from its various angles as well as a comparison of different techniques and applications. An essential source of high quality information for everyone working in this booming and interdisciplinary field: spectroscopists, physical and inorganic chemists as well as materials scientists working in nanotechnology and the pharmaceutical industry.

Synthesis, Crystal Growth and Characterization presents the proceedings of the International School on Synthesis, Crystal Growth and Characterization of Materials for Energy Conversion and Storage, held on October 12-23, 1981, at the National Physical Laboratory in New Delhi, India. The book consists of lectures by distinguished scientists from around the world who tackle different aspects of synthesis, crystal growth, characterization of materials, energy conversion, and energy storage. Organized into four parts encompassing 26 chapters, the book begins with an overview of the synthesis of materials at high temperatures and pressures before turning to a discussion of how macrocrystalline and amorphous silicon is prepared. It then looks at fundamental principles underlying the process of crystal growth, both from the vapor phase and from melt, and methodically introduces the reader to the different techniques used to characterize materials, including neutron scattering and electron transport. The next chapters focus on point defects and aggregates that influence the critical electronic properties of semiconducting materials, X-ray diffraction studies of strains and stresses in thin films used in solid-state devices, and electron spectroscopic studies of solid surfaces. The book also considers the role of physics in microelectronics and vice versa, fast ion transport in solids, and the concept of Syadvada in relation to modern physics. This volume is a valuable resource for participants of the International School on Synthesis, Crystal Growth and Characterization of Materials for Energy Conversion and Storage, as well as active researchers working in areas related to the field.
