Programs and Accomplishments
The Ceramics Division's technical
activities in fiscal year 2005 were focused on cutting-edge
metrology and standards efforts, particularly in nanometrology
and materials for electronics. This report reviews those
efforts and presents progress reports on our mission-oriented
projects on advanced measurement capabilities, evaluated data,
and standards. To learn more about these research activities,
please see the

Dr. Andrew
Allen, Physicist, Ceramics Division, published a featured
paper, entitled
"Characterization of Ceramics by X-ray and Neutron
Small-Angle Scattering" Journal of the American Ceramics
Society, 88[6], 1367-1381 (2005).
This
paper reviews some recent advances in small-angle X-ray and
neutron scattering methods and their application to address
complex issues in ceramic systems of technological importance.
It is shown how small-angle scattering (SAS) can be applied to
ceramic systems in order to extract statistically representative
microstructure information (e.g., void volume fraction size
distributions, internal surface areas, pore morphologies) that
complements the information obtained from diffraction methods,
X-ray microtomography, or electron microscopy. It is demonstrated
how SAS studies provide insights, not obtainable by other means,
on the processing-microstructure-property relationships that
frequently govern technological performance.
