Hydrothermal Reactions For Materials Science And Engineering

According to the late Professor Emeritus Seitaro Tsuboi,l the word 'hydrothermal' was used as early as 1849 by a British geologist, Sir Roderick Murchison (1792-187 I), in relation to the action of heated water in bringing about change in the earth's crust. The term abounds in later geological literature, and is most frequently met in connection with the processes that take place at a stage near the closing in the course of consolidation of magma. When a cooling magma reaches that stage, the residual liquid contains a large proportion of volatile components, chiefly water, and further cooling results in the formation of minerals of special interest or ore-deposits. A great concern of Tsuboi's as a petrologist was to elucidate the details of the nature of various actions involved in these 'hydrothermal processes', of which little was known. It is remarkable that, in the last few decades, extensive high-temperature and high-pressure experiments, in which water plays an important role, have become practicable in laboratories, owing to the development of new apparatus and new methods. As a result, the knowledge essential to the elucidation of 'hydrothermal processes' has been improved, but is still far from complete.

Hydrothermal techniques have been widely used in the synthesis of advanced materials, the treatment of wastes, and the preparation and extraction of special chemicals. They have also been studied for the mimicking of geothermal processes. Nowadays, hydrothermal techniques and sciences play a very important role both in industry and in academia. This book includes contributions from chemists and chemical engineering scientists worldwide who are active in the field of hydrothermal reactions and techniques. The topics covered range from fundamentals of hydrothermal reactions, modeling of hydrothermal processes, new techniques for hydrothermal treatment, and new materials from hydrothermal systems to supercritical fluid reaction systems.

This symposium was organised with the aim of encouraging collaboration in international science and engineering communities for the benefit of human kind. It consisted of invited talks by experts on materials and poster presentation papers. Approximately 140 scientists participated and the resulting proceedings present an up-to-date review of the research in this area.

Frontiers of Materials Research/Electronic And Optical Materials: Volume I is part of a five-volume compilation of the proceedings of C-MRS International 1990 Conference held in Beijing, China. The said conference discusses the areas of research in materials science. The book is divided into three parts. Part 1 covers topics involved in the development and progress of materials such as the focused beam ion; intermetallic compounds; polymers; and the application of computers in the field. Part 2 includes studies related to high Tc superconductors such as methods related to the field; the effects of oxygen and partial pressure on the properties of superconducting; and the study of superconductivity and crystallography. Part 3 presents papers related optoelectronic materials and functional crystals, which are mostly about the growth, properties, and uses of the different crystals being studied in each paper. The text is recommended for scientists and engineers who would like to know more about the field of materials science, especially those who would like to be involved in materials research.

Although ceramics have been known to mankind literally for millennia, research has never ceased. Apart from the classic uses as a bulk material in pottery, construction, and decoration, the latter half of the twentieth century saw an explosive growth of application fields, such as electrical and thermal insulators, wear-resistant bearings, surface coatings, lightweight armour, or aerospace materials. In addition to plain, hard solids, modern ceramics come in many new guises such as fabrics, ultrathin films, microstructures and hybrid composites. Built on the solid foundations laid down by the 20-volume series Materials Science and Technology, Ceramics Science and Technology picks out this exciting material class and illuminates it from all sides. Materials scientists, engineers, chemists, biochemists, physicists and medical researchers alike will find this work a treasure trove for a wide range of ceramics knowledge from theory and fundamentals to practical approaches and problem solutions.

Many believe that the silicon/information age is heading to the Age of Biology and that the next frontier in ceramics will most likely require molecular level or nanoscale control. What, then, is the role of ceramics in the age of biology? As we change from an energy-rich society to an energy-declining society, how can ceramic materials appease the problem? This new edition of Chemical Processing of Ceramics offers a scientific and technological framework for achieving creative solutions to these questions. Edited by experts and containing chapters by leading researchers in the field, the book uses an interdisciplinary approach to cover topics ranging from starting materials to device applications. The book begins with a discussion of starting material, highlighting how to prepare and modify them in the nanoscale range. The chapter authors discuss the synthesis, characterization, and behavior of ceramic powders, the processing of ceramic films via sol-gel technique, and the fabrication of nonoxide ceramics. They also present coverage of several specific thin films, membranes, ferroelectrics, bioceramics, dieletrics, batteries, and superconductors. Although the book is edited, it is organized to reflect the chemical sequence of ceramic processing and the coherent theme of chemical processing for advanced ceramic materials. The coverage of molecular/nanoprocessing techniques that result in new materials will enable researchers and engineers to meet the challenge of producing inorganic materials for use in the applications of the future.
