High Pressure Explosive Processing of Ceramics Edited by R.A. Graham and Akira B. Sawaoka This book comes as a beacon of potential for new materials development using a rather bizarre fabrication scheme. Dick Spriggs' overview of the book in Chapter 2 provides an essential roadmap for the reader, and the book really cannot be appreciated without first reading this chapter since it provides some essential context. Spriggs concludes, "Commercial products are not yet known from the foregoing shock-enhanced sintering techniques. However, such methods hold considerable promise, and several later chapters of this book are devoted to these processes." The 12 chapters following Spriggs' introductory remarks present some interesting prospects and proposals. It is standard practice to develop a book review based on the presumption of content by the reviewer or a summary of the chapter content. This review will deviate from this routine because it is not so much the content of the book that is novel and important as the concept and the context in which it was written. To quote the editors' Preface, "The present book was edited and published to bring together the threads of a wide ranging and significant materials research area which has had limited visibility because publications are widely scattered among a number of sources." But, the book does more than just bring together threads. It provides some intriguing possibilities for materials modification and synthesis, particularly ceramic materials, using the unique features of the highpressure state. Readers already familiar with ceramic powder processing will be particularly intrigued by the prospects for enhancing conventional processes by subjecting powder to a shock wave prior to processing. It is these fundamental issues which constitute these threads of materials research.
While the book might appeal to anyone interested in novel materials research, it will be particularly rewarding for students and researchers in ceramic science who are not necessarily experts in high-pressure physics. In this context, it may indeed "stimulate and guide future research activities" as the editors conclude in the preface. The only notable shortcoming of the book is its rather short index, a little disconcerting for a more knowledgeable materials researcher who may want to locate particular topics within the book. But the reviewer looked at the chapters as a kind of sampler rather than a reference resource, and the book is more interesting to browse through than to consider as a more traditional reference book. It is recommended reading for a wide range of materials scientists and engineers.
tion, DI water filtration technology, and the technology of producing ultrapure gases. Each chapter gives an outstanding review of the state-of-the-art technology, with extensive lists of references to the pertinent literature. The chapter on aerosol filtration technology, by D. Ensor and R. Donovan, reviews the basic fundamentals of filtration technology with a good summary of the theoretical expre
