Comparison of results between laser diffraction and image analysisLaser diffraction is a popular method for particle characterization. Coupled with an image analysis unit, we can compare in real time the classical values of D10, 50, 90 and get information about the shape or dispersion state of our particles, thus proving the usefulness of this complementary technique.
Optimization of High-Performance Nanostructured Powder Metallurgy MaterialsIn this note, we will briefly explore the history of powder metallurgy and then examine the importance of powder quality to the production of nanomaterials.
Metal Powder Properties: A Case with Low Specific Surface AreaDetermination of specific surface area of metal powders is an important parameter in the field of powder metallurgy. In this note, we demonstrate the use of Brunauer-Emmett-Teller (BET) technique to measure another critical metal powder property: specific surface area (SSA).
Metal Powder Size MeasurementVirtually any metal can be made into a powder through processes including atomization, electrolysis, chemical reduction, and size comminution. The metal powder can then be used to fabricate parts from simple to complex shape. The technique and study of these processes is known as powder metallurgy, a field of study well acquainted with particle characterization. The size distribution and shape of the powder metal particles influences the physical properties of the parts created.
