Dispersion of Powders


Book Description

Teaching the fundamental knowledge required for successful dispersion of powders in a liquid, this book covers a host of topics -- from recent advances to industrial applications. In 15 chapters it supports formulation chemists in preparing a suspension in a more rational way, by applying the principles of colloid and interface science, while at the same time enabling the research scientist to discover new methods for preparing stable suspensions. Essential reading for those working in the pharmaceutical, cosmetic, food, paint, ceramic and agricultural industries.







Particle Size Measurements


Book Description

This book focuses on the practical aspects of particle size measurement: a major difference with existing books, which have a more theoretical approach. Of course, the emphasis still lies on the measurement techniques. For optimum application, their theoretical background is accompanied by quantitative quality aspects, limitations and problem identification. In addition the book covers the phenomena of sampling and dispersion of powders, either of which may be dominant in the overall analysis error. Moreover, there are chapters on the general aspects of quality for particle size analysis, quality management, reference materials and written standards, in- and on-line measurement, definitions and multilingual terminology, and on the statistics required for adequate interpretation of results. Importantly, a relation is made to product performance, both during processing as well as in final application. In view of its set-up, this book is well suited to support particle size measurement courses.

Particle Size Analysis


Book Description

teacher Professor Ernst-Joachim Ivers to whom I still owe many insights 20 years after the end of his working life. This English edition is not an unedited translation of the German edition of 1990. The text has been substantially revised in some chapters, taking into account the literature published in the mean time. I wish to thank Dr.-Ing. H. Finken, Freiberg, who has prepared the translation from German into English with deep scientific understanding and in close contact with the author. I also wish to express my gratitude to Chapman & Hall for their support to this project without which the English edition could not have been published. Dr.-Ing. habil. C. Bernhardt Freiberg 1 Position, tasks and structure of particle size analysis Today the concept of particle size analysis is that of a special field of particle measurement technology, which in turn is part of particulate technology. This classification has developed over the last 20 years; it is the result of a scientific integration process taking place in many industrialized countries of the world. In recent years, the meaning and mutual connection of the related concepts as well as the tasks of the scientific disciplines designated by them have been the subject of intensive discussion which, however, has not led to a generally accepted terminology.




Powder Metallurgy of Superalloys


Book Description

Powder Metallurgy of Superalloys details the advancement of powder metallurgy in the context of producing superalloys. The book is comprised of nine chapters that cover the underlying principles of superalloys produced through powder metallurgy. The text first covers concerns in pre-alloyed dispersion-free powders, such as powder production and characterization; powder consolidation methods; and quality control and non-destructive evaluation of P/M superalloys. The next chapter talks about oxide-dispersion-strengthened superalloys. Next, the book discusses joining techniques for P/M superalloys and the practical applications of P/M superalloys. The title will be of great use to professionals in the materials manufacturing industry.




Surface and Colloid Chemistry in Advanced Ceramics Processing


Book Description

Emphasizes the importance of surface and colloid chemistry in the manufacture of high-performance ceramics. Examines processing-property relationships, powderproductionandcharacte6zation,the dispersion properties of powders in liquids, the rheology of concentrated suspensions, and the surface and colloid chemistry aspects of the most widely used forming methods.




Practical Dispersion


Book Description

Ein Handbuch für die Praxis der Dispersionstechnologie: Weitverstreute Daten aus der Literatur, technische Details und ausgewählte theoretische Grundlagen wurden zu einer übersichtlichen, gut verständlichen Darstellung aufbereitet, die nicht mit Mathematik und komplizierten Zusammenhängen überfrachtet ist. An zahlreichen Beispielen wird erklärt, wie sich verschiedene Dispersionszustände in den Eigenschaften des Produkts widerspiegeln; die Wirkung eines Dispersionsmittels wird auf stoffliche Aspekte, nicht Handelsnamen zurückgeführt. Der Anwender wird in die Lage versetzt, 'seine' Dispersionen gezielt zu verändern, um mechanischen, chemischen und ökologischen Anforderungen der Kunden gerecht zu werden. Mit Herstellerlisten für die technische Ausrüstung! Geschrieben in erster Linie für die industrielle Praxis - weniger für akademische Forschung und Lehre.




Particle Size Enlargement


Book Description

Handbook of Powder Technology, Volume 1: Particle Size Enlargement is the first of a series which will together form a Handbook of Powder Technology, primarily intended for engineers and scientists working in industry. The scope of the Handbook can be defined as being concerned with that part of chemical engineering which deals with processes involving the handling and treatment of material in solid particulate form. This book deals with methods used to create larger entities from fine particles so that the bulk properties of particulates can be improved. These so-called ""size enlargement"" methods evidently concern a broad spectrum of technical disciplines and industries ranging from the relatively small scale requirements of pharmaceutical manufacturers through the tonnage requirements of the fertilizer and minerals processing industries. A primary objective in preparing this book was to present a generalized account of the many size enlargement techniques scattered throughout these diverse industries, with emphasis on similarities and unifying characteristics whenever possible. The book devotes one chapter to each of the principal methods used to bring particles together into agglomerates: agitation methods— tumbling agglomeration, agitation methods—mixer agglomeration, pressure methods, thermal methods, spray and dispersion methods, and agglomeration from liquids.




Particulate Interactions in Dry Powder Formulation for Inhalation


Book Description

Interactions between drug particulates are crucial in determining drug dispersion and deaggregation, and ultimately delivery efficiency. This book combines principles established in surface and colloidal chemistry with pharmaceutical powder technology. It discusses some of the factors affecting particulate interactions, and particle-fluid interaction in the respiratory tract. It review some of the studies carried out in dry powder formulation development, and proposes possible strategies in improving DPI efficiency. The majority of these principles are applicable to other pharmaceutical solid dosage forms (e.g. tablets and capsules).
