Successful performance of a powder for a speciﬁc application depends on the compatibility between the production process and a variety of powder characteristics. In this intensive course different qualiﬁed methods for characterisation of powders are presented and related to powder handling and functionality. The aim of the course is to provide participants with a better understanding of different techniques available today and in near future for characterization that opens for a needed further understanding and standardization of powders.
The course covers three full days of lectures and round table discussions. Participants will be divided in smaller groups and the round tables will focus on speciﬁc themes. This provides participants with an opportunity to deepen their knowledge in speciﬁc ﬁelds and to exchange experience with others from different areas of work. Participants will be asked to submit questions and their own problems prior to the start of the course. Their speciﬁc questions will be highlighted during the course.

Size, shape, morphology and size distribution of powder particles:
- Introduction to size, shape and morphology – why important?
- Laser diffraction particle sizing
- Powder image analysis
- Electron microscopy techniques (e.g. SEM, TEM, X-ray powder diffraction, environmental SEM)
Material properties of powders:
- Energy-dispersive X-ray spectroscopy
- Calorimetric methods
The day ends with two Round tables: Particle size mapping and Electron microscopy, where also participants’ cases will be discussed.
Surface chemistry of powders:
- Introduction - why is the surface chemistry important for powders?
- The MAX IV facility
- Overview of different types of X-ray techniques
- Advantages of using synchrotron light compared with standard laboratory methods
Application examples of characterization of surface chemistry of powders:
- X-ray photoelectron spectroscopy (XPS/ESCA )
- Raman spectroscopy and Confocal imaging
- Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS)
- FT-IR spectroscopy: Attenuated Total Reﬂectance (ATR)
The second day will be held at the MAX IV laboratory. MAX IV is the ﬁrst 4th generation synchrotron source in operation and with world-leading brilliance and ﬂux. The facility will support a wide range of experimental techniques such as macromolecular and time resolved crystallography, synchrotron X-ray powder diffraction (SR-XRPD) and energy dispersive X-ray diffraction, small-angle X-ray scattering (SAXS) and 3D X-ray diffraction tomography, among others. The use of synchrotron radiation to address industrial problems is growing rapidly worldwide. The high brilliance of MAX IV is ideal for using X-ray scattering in the study of equilibrium and non-equilibrium dynamics in both soft and condensed materials. The high ﬂux will improve energy and spatial resolution beyond those of current facilities.
The day ends with two Round table discussions “Characterization of surface chemistry of powders” and “From questions to results – how to cooperate with MAX IV?”.
Flow properties of powders:
- Overview of different analytical techniques with focus on Mohr circle analysis
- A multivariate approach to characterise powders’ rheological properties
- Particles in air - characterization of aerosolization properties
- Tomography – microstructure of powders
Reconstitution properties of powders:
- The powder bed and wetting properties
- The sessile drop technique applied on a powder bed
- Image analysis
Björn Bergenståhl, professor in Food Technology at Lund University since 1998. For more than 15 years, he worked as researcher and section manager at YKI Institute for Surface Chemistry in Stockholm. He has a long-term experience in applied surface and colloid chemistry in industrial systems (chemical technical, paint, paper, mining, pharmaceutical and food industry) and on surface properties of solid systems obtained through drying. Another area of interest is the inﬂuence of the surface physics on the functional properties of industrial powders (wettability, dispersability and ﬂowability).
