Abstract Computer-controlled scanning electron microscopy (CCSEM) is a technique that allows rapid, automated characterization of the size, shape and chemistry of large numbers of individual particles. When complemented with recently developed microimaging technology, CCSEM can store the location and characteristics of a specific particle for subsequent retrieval. The ability to detect particles and map their locations is especially useful when certain particles (impurities, for example) are sought.

Abstract As the interest in parts fabricated from powders grows, so does the technology related to research in the field. The analytical electron microscope (AEM) is a particularly powerful tool for characterizing fine particulates. The AEM can provide detailed information on the microstructure of powders and the final parts, allowing control of the ultimate properties.

Abstract As characterized by scanning and transmission electron microscopy, the microstructure of carbonyl iron powder is that of an expanded a-iron lattice containing carbon, oxygen and nitrogen, having a high internal stress, but no martensite phase. This fine, spherical powder is made by the thermal decomposition of iron pentacarbonyl. In the laboratory, particle size distribution has been characterized by image analysis and laser light scattering techniques. Data on narrow particle size distributions has been obtained, including electrical (P and Q) values, and compared to standard grades. As a result, the relationship of the decomposition process to the resulting metallurgical properties can be explored.

Abstract As society places pressure on governmental agencies to protect the environment, new legislation and regulations are forcing industry to handle and dispose of dangerous materials responsibly. Safe, ecological behavior has a cost, however, and new technologies must often replace or augment the old way of doing things. While some of the less expensive measures have already been commercialized, much of the new technology is still in the developmental stage.
