Introduction
Metal powder metallurgy is the study of transforming metal into powder and the consolidation of powder into desired final product through methods such as sintering, compaction, blending, injection molding, or extrusion. Powder metallurgy is the essence of 3D additive manufacturing [1] and it covers a broad spectrum of traditional applications including orthopedic implants, dental restorations, or paint pigments. The success of any powder metallurgical process, however, depends heavily on the understanding and control of the metal powder characteristics.
In Applications Note 164, “Particle Size and Shape Analysis of Powder Metals [2],” we demonstrated how powder manufacturers used laser diffraction and imaging analysis techniques to set size and shape metrics for powder grades and classifications. In this note, we demonstrate the use of Brunauer-Emmett-Teller (BET) technique to measure another critical metal powder property: specific surface area (SSA).
