Book Description
The report describes the design, installation, calibration, and test of a unique high pressure, high temperature crystal growth system of the Solid State Sciences Laboratory of Air Force Cambridge Research Laboratories. A number of modifications and innovations that make the system unique are described. Pictures and diagrams of the crystal growth system are sufficiently complete to provide substantial aid in the operation or duplication of this facility. This furnace has been operated above 3000C at internal pressures of twenty atmospheres and at a vacuum in the low 0.00001 Torr range. (Author).

Book Description
A high-pressure, high-temperature furnace system is described for crystal growth experiments using crucibles up to 13 cm in diameter and 26 cm high. The vertical temperature gradient is electronically controlled during growth such that the ends of the crucible can be maintained at temperatures above or below the crucible center. Temperatures up to 2800C can be maintained at pressures up to 50 atmospheres. A vacuum capability up to .000001 torr at 1800C has been incorporated into the system. Single crystals of alpha silicon carbide grown in this system at 2600C are described to illustrate its use. (Author).

Book Description
High pressure technology is used so extensively that it is almost impossible to catalogue the manyways in which our lives are enhanced by it. From pneumatic tires and household water supplies tomaterials such as crystals, plastics, and even synthetic diamond, there are countless materialsfabricated or shaped using high pressure technology. High Pressure Technology (in two volumes)presents the most up-to-date information available on the main features of this broad technology andthe processes which utilize it.Volume I: Equipment Design, Materials, and Properties covers three broad areas: the general operationof high pressure systems, including standard operating procedures and safety codes and measures;the technology of high pressure systems, such as components, vessel design, and materials of construction;and applied science at high pressure, including the properties of fluids and solids andmechanical properties. Volume II: Applications and Processes covers processes at high pressure andencompasses such topics as: catalytic chemical synthesis; polymerization; phase changes; criticalphenomena; liquefaction of gases; synthesis of single-crystal materials, diamond, and superhardmaterials; isostatic compacting; isostatic hot-pressing; hydrostatic forming of metals; hydraulic cutting;and applications of shock techniques.Written by recognized authorities in industry, government laboratories, and universities, High PressureTechnology is essential reading for the industrial practitioner, high pressure engineer, and researchscientist. In addition, it is a valuable textbook for students in mechanical, chemical, and materialsengineering courses.

Book Description
Volume 41 of Reviews in Mineralogy and Geochemistry introduces to the field of high-temperature and high-pressure crystal chemistry, both as a guide to the dramatically improved techniques and as a summary of the voluminous crystal chemical literature on minerals at high temperature and pressure. The three parts of the book introduces crystal chemical considerations of special relevance to non-ambient crystallographic studies, reviews the temperature- and pressure-variation of structures in major mineral groups and presents experimental techniques for high-temperature and high-pressure studies of single crystals and polycrystalline samples as well as special considerations relating to diffractometry on samples at non-ambient conditions.

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
