Aerosol Processing of Materials

Unifying a wide range of materials synthesis techniques, 'Aerosol Processing of Materials' provides a detailed overview of the production of materials by the use of gas phase processes. Aerosol processes are responsible for the production of many of today's most advanced materials, especially in the semiconductor, optical waveguide, and thin film industries. Many of the unique properties of nanophase materials and composites are only possible through the application of acrosol in materials processing. This book describes various types of aerosol processes and the role of aerosols in materials processing. The work presents the advantages and disadvantages of each process in terms of cost, complexity, purity, and materials properties; and compares these factor to alternative methods of powder and film formation. The title provides the theory needed to understand and advance the fundamentals of this rapidly expanding material manufacturing processes. Written by well-respected leaders in the field, the book illuminates the roles of particle size characterization and size distributions; heat, mass, and momentum transfer; particle transport; condensation and evaporation; and coagulation and coalescence. 'Aerosol Processing of Materials' provides the most up-to-date and comprehensive single source of information available on gas-to-particle powder formation; liquid/solid-to-solid powder formation; film formation; reactor design; and particle/film characterization.Zu den mit Hilfe von Aerosoltechniken hergestellten Produkten gehören Pigmente, Supraleiter, Sensoren, Hochtemperaturbeschichtungen und Lichtwellenleiter. Dieses Buch deckt alle Aspekte des Fachgebietes ab, von der Chemie der Aerosole über Verarbeitungsverfahren bis hin zur Vermessung der abgeschiedenen Materialien. Durch eine geschickte Organisation des Textes läßt sich das Buch auch hervorragend als Nachschlagewerk für die behandelten Beispiele, Aufwachsprozesse und Reaktormodelle verwenden.

Aerosol Processing of Materials offers a comprehensive look at advanced materials processing by aerosol methods. This self-contained volume examines in-depth what it takes to generate powders and films with specialized characteristics using gas-phase processes. In three main parts, it addresses particle formation by intraparticle reaction, particle formation by gas-to-particle conversion, and film formation. All aspects of these subjects are considered, from the basic principles and chemistry of aerosols to processing methods and the characterization of materials. The text incorporates an impressive array of examples involving materials such as metals, metal oxides, and metal sulfides for application in pigments, ceramics superconductors, electronics, sensors, glass coatings, semiconductors, optical materials, and thick films.

Fully referenced, generously illustrated, and lucidly written by two of the foremost authorities on aerosol processing of materials, this landmark work emphasizes cutting-edge technologies, industrial applications, and the need to put existing research to practical use.
