Investigations into methods of photometric measurement of surface area and average diameters of fine particles. Charles, Richard Joseph Thor
Abstract
The problem of surface area and particle size determination has been examined. A survey of the methods for measuring the surface areas and average sizes of aggregates of fine particles was made and a method selected for Improvement. An apparatus employing the principles of fine particle measurement established in turbidimetry was constructed. Experimental work with the apparatus was conducted in an attempt to establish a single method of particle size measurement. The results warrant the conclusion that the apparatus will measure average surface diameters of single component materials, constant assaying materials, and mixtures containing one semi-transparent material. A value for the relative surface area of these materials can also be determined.
