All three or four phases of dispersion or dissolution are proceeding individually whereby some overlapping may occur, depending on the amount of material involved. Instant properties are a function of time. Each industry has a more or less well defined procedure to determine the maximum allowable time. Typically, complete dispersion or dissolution should be accomplished within a few seconds in warm liquid and in approx. 30-60 s in cold liquid. Particularly in the food and pharmaceutical industries, instant agglomerates may contain certain substances that assist in the break-up during the dispersion phase (see Section 5.1.2, Fig. 5.13). In the pigment and chemical industries dispersion is often assisted by some sort of agitation [B.51].

The dispersion time is proportional to the energy consumption of a dispersion machine and should, therefore, not exceed the needed value. If possible, the dispersion kinetics is described in terms of energy, which may allow up-scaling from laboratory to industrial dispersion processes. 

Electrochemically and chemically produced metal powders from aqueous solutions are of high purity. These powders find applications in metallurgy, automotive, aerospace, energy device, electronics, and biomedical industries. Disperse deposits and electrochemically produced metal powders are also very suitable for use as catalytic surfaces in chemical industry. 

Currently, both FT-Raman and dispersive Raman spectrometers are being used within the pharmaceutical industry. Dispersive Raman spectroscopy in the form of Raman microprobes are heavily employed in the research area to map active-excipient distribution using the diffraction limited spatial resolution attainable with the microprobe. In this subsection, it is inappropriate to describe the varied applications of Raman microscopy to the study of pharmaceuticals thus, the reader is referred to the literature [108,109] and Chapter 14. Dispersive Raman analyzers are also being used for reaction analysis, pilot-plant batch analysis, and process monitoring. FT-Raman spectrometers have been adopted for formulated product analysis and for incoming goods testing. 

A suspension, or periuq>s more broadly a dispersion, consists of discrete particles randomly distributed in a fluid medium. Gen erally we divide suspensions into three categories solid particles in a liquid medium (often the word suspension is restricted to this meaning), liquid droplets in a liquid medium (or an emulsion), and gas in a liquid (or ifoam). All these categories have great practical importance, from biological materials like milk and blood to paint, ink, ceramics, and many other industrial dispersions. 

The standard method of moments (MOM) which was first developed by Randolph and Larson [187] and Hulburt and Katz [90]. The standard MOM solves the PBM problem by tracking the time dependence of the lower-order moments of the distribution [90, 151]. The moment methods thus involve the conversion of the PBE for the number density distribution function itself to equations in terms of the moments of the number density distribution function. The lower-order moments are often considered sufficient for estimating the physical properties of many industrial dispersions, whereas the full particle number density distribution might contain more information than is strictly required for such applications. Conversely, the lower-order moments of a dispersion particle number density distribution may be inferred from measurements and compared with the moments obtained from simulations using the MOM.
