SPECIFIC SHAPE CHARACTERIZATION OF CARBON BLACK PRIMARY UNITS.

Abstract

A full field feature specific image analysis system has been developed for direct morphological characterization of carbon black in the electron microscope. The system provides quantitative size and non-dimensional shape information as well as qualitative classification into specific shape categories using pattern recognition programming methods. Data on samplings of 500-1000 primary black units can be recorded on magnetic tape in less than 10 minutes. The new image analysis system also has the capability of volume measurements based on microdensitometry.
