Название: Powder Surface Area and Porosity
Автор: Lowell S.
An increasing number of industries now deal with materials in powder form. The surface area and porosity of powders are characteristics of particular importance in their industrial use. The previous edition of "Powder Surface Area and Porosity" continues to provide an introduction to the experimental methods used to study these properties and a handbook for those needing practical guidance on measurement of surface area, density, particle size and pore size. Particular features in this edition include an extended discussion of micropore analysis and an introduction to methods of particle size measurement, including sedimentation techniques. Part I of the book covers the important theories associated with the measurement of surface area and porosity, discussing gas adsorption, Langmuir and Brunauer, Emmett and Teller theories, adsorbate cross-sectional areas, Harkins and Jura methods, pore analysis by adsorption, microporosity, mercury porosimetry and sedimentation techniques. Part II describes and compares various experimental methods, including vacuum volumetric measurements, dynamic gravimetric and adsorption methods, mercury porosimetry, density measurements and sedimentation techniques. This book should be of interest to powder technology specialists in industry and academia, and graduate students in chemical engineering.
