Particle Size Analysis

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.

Texte du rabat

This text will be of interest to all those concerned with the preparation, processing and analysis of disperse systems. There is a wide range of methods and devices available for providing information on the quantitative distribution of the characteristics of particle size and shape obtainable: choosing which one is not easy. This work will prove to be an invaluable source of reference for powder technologists, as well as graduates and researchers.

Résumé
The book provides a thorough grounding in theories and concepts of particles size analysis...The book is well written and is recommended to everyone involved in powder technology, chemical engineering and material science. - La Chimica et L'Industria
I particularly liked the section on colloids - the equations are very well defined and the units are specified, which is regrettably, not all that common. Yes, I will buy our sizing laboratory its own copy and recommend it to our library! - Chemistry and Industry
