Extractive Metallurgy Of Titanium

Extractive Metallurgy of Titanium: Conventional and Recent Advances in Extraction and Production of Titanium Metal contains information on current and developing processes for the production of titanium. The methods for producing Ti metal are grouped into two categories, including the reduction of TiCl4 and the reduction of TiO2, with their processes classified as either electrochemical or thermochemical. Descriptions of each method or process include both the fundamental principles of the method and the engineering challenges in their practice. In addition, a review of the chemical and physical characteristics of the product produced by each method is included. Sections cover the purity of titanium metal produced based on ASTM and other industry standards, energy consumption, cost and the potential environmental impacts of the processes. Provides information on new and developing low cost, high integrity methods for titanium metal production Discusses new markets for titanium due to the decreased cost of newly developed processes Covers specific information on new methods, including the chemical and physical characteristics produced

This new book covers all aspects of the history, physical metallurgy, corrosion behavior, cost factors and current and potential uses of titanium. The history of titanium is traced from its early beginnings through the work of Kroll, to the present day broadening market place. Extensive detail on extraction processes is discussed, as well as the various beta to alpha transformations and details of the powder metallurgy techniques.

The authors were motivated to prepare this book by the absence of any recent comprehensive book on titanium. The intent of this book is to provide a modern compendium that addresses both the phyical metallurgy as well as the applications of titanium. Until now the only book on this subject is that by Zwicker which was written in German and published almost 30 years ago. Chapter 1 is an introduction to the subject including some historical aspects of titanium. Chapter 2 is a s- mary of the Fundamental Aspects of Titanium, Chapter 3 is a summary of the Technological Aspects of Titanium and Chapters 4 through 9 address the specifics of the various classes of titanium ranging from CP Titanium to Titanium Matrix Composites. Finally, Chapter 10 covers “special” properties and applications of titanium. Our intent has been to address the subject conceptually rather than provide quantities of data of the sort that would be found in a Handbook. It is our intent that this book is useful for materials scientists and engineers interested in using titanium and for students either as a sourcebook or as a textbook. We have - tempted to include a representative set of references which provide additional detail for readers interested in specific aspects of titanium. Because of the re- tively recent growth of the technological importance of titanium, there is a vo- minous literature on titanium. While our references span this literature it has proven impossible to mention every contribution.

The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.

Extractive metallurgy is the art and science of extracting metals from their ores and refining them. The production of metals and alloys from these source materials is still one of the most important and fundamental industries in both developed and developing economies around the world. The outputs and products are essential resources for the metallic, mechanical, electromagnetic, electrical and electronics industries (silicon is treated as a metal for these purposes). This series is devoted to the extraction of metals from ores, concentrates (enriched ores), scraps, and other sources and their refining to the state of either liquid metal before casting or to solid metals. The extraction and refining operations that are required may be carried out by various metallurgical reaction processes. Extractive Metallurgy 1 deals with the fundamentals of thermodynamics and kinetics of the reaction processes. Extractive Metallurgy 2 focuses on pyrometallurgical, hydrometallurgical, halide and electro-metallurgical (conversion) processes. Extractive Metallurgy 3 deals with the industrial processing operations, technologies, and process routes, in other words the sequence of steps or operations used to convert the ore to metal. Processes and operations are studied using the methodology of “chemical reaction engineering”. As the fundamentals of the art and science of Extractive Metallurgy are infrequently taught as dedicated university or engineering schools courses, this series is intended both for students in the fields of Metallurgy and Mechanical Engineering who want to acquire this knowledge, and also for engineers put in charge of the operation of an industrial production unit or the development of a new process, who will need the basic knowledge of the corresponding technology.

The conference upon which this work is based fully achieved its objectives and turned out to be the largest international gathering dedicated solely to the topic of titanium processing via powder metallurgy. Volume is indexed by Thomson Reuters CPCI-S (WoS). The 50 peer-reviewed papers are grouped into 8 chapters: PM titanium alloy design and processing developments; Powder Production; Effect of Impurities; Metal Injection Moulding of Titanium; Biomedical Titanium Alloys; Titanium Composites; Forging and Equal-Channel Angular Pressing of Titanium; Laser Cladding, Welding, Slip Casting and Other Processing Developments.

This publication addresses the latest developments andbreakthroughs in all areas of science and engineering of titaniumtechnology that aim to reduce the cost of titanium for end users.The broad areas covered include: Extractive Metallurgy Melting Casting and Refining Practices Powder Processing and Handling Deformation Processing Alloy Development Microstructure and Property Enhancement Through SecondaryProcessing Emphasis is given to those processes that are under developmentand/or emerging as well as innovative A collection of papers from the ahref="http://www.tms.org/Meetings/Annual-07/AnnMtg07Home.html"target="_blank"2007 TMS Annual Meeting & Exhibition/a heldin Orlando, Florida, February 25–March 1, 2007.
