Morphological analysis particulate material

This paper is a brief review of original basic engineering research in morphological analysis applied to particle characterization which has been conducted during the last 20 years at the University of Iowa, Center for Particulate Material Processing Sciences. The topics discussed include definitions, theory, instrumental and experimental aspects of size, shape and texture measurements of particulate material. 

Morphological analysis is concerned with particle characterization in the case of particle size, particle shape and particle texture. Particle texture may deal with the particle surface characteristics and also with the particle microstructure. Particle size and shape influence physical and chemical properties of particulate materials. Morphological analysis is being developed in order to facilitate a more accurate description of the properties and behavior of particulate systems from a fundamental knowledge of the characteristics of the particles of the system [1,2]. 

The hypothesis affirms the need to characterize the material s physical and chemical properties, including morphological analysis. The latter has significant ramifications on the aerodynamics of the particulate matter and hence its ultimate disposition. 

The importance of structural disorder in the metal is considered and the behaviour of well annealed material is compared to structurally less stable but clean metal surfaces. The processes that occur in the development of particulate deposits have been followed. Auger analysis of individual morphologies has highlighted particular problems in the analysis of carbon deposits after ion etching.
