Controlling the Impact of Humidity Using the FT4 Powder Rheometer®
Introduction The properties of dry and damp powders can be as dissimilar as those of chalk and cheese. The uptake of even small amounts of moisture can transform powder properties, making humidity and its impact a critical issue for powder processors. While steps can be taken to control moisture level, by drying the material ahead […]
Assessing Batch-to-Batch Variability of Bulk Chemicals Using the FT4 Powder Rheometer®
Introduction Titanium Dioxide has been used as a pigment and opacifier in a wide range of industries for many years, due to its bright white color and high refractive index. However, despite such widespread use, processing Titanium Dioxide in its powdered form is often extremely challenging due to the powder’s high cohesivity. Special measures often […]
Developing a Design Space for Powder Characterization
Anytime a powder is used in a process for a specific purpose, its behavior is often predicted by physical properties of the powder. Determining the physical properties of a cathode powder can be used to decide which properties are critical to the performance of the cathode, as well as the battery in which it is used. A sample of lithium iron phosphate (LFP) powder was characterized to determine […]
Building Robust Pharma Physical Properties Analysis
Broaden your understanding of solid form analysis. Traditionally a limited number of techniques have been used for physical properties analysis. Now, the opposite is becoming the issue, there are a multitude of good and reliable techniques, that can enrich solid form analysis. By looking at examples of porosity, surface area and powder flow analyses, we […]
Measurement and Quantification of Caking in Powders
Many powders have the potential to cake during storage. As the strength of particle-particle interactions increases, especially via mechanisms involving moisture, the flow characteristics of the material are compromised, detrimentally impacting performance and value. Caking may be preventable or easily addressed through the adoption of well-defined protocols, for example, storing the material in a closely […]
Powder Characterization Tools for Evaluating Polymer Powders for Laser Sintering
Which properties are important when assessing polymer powders for Laser Sintering? Enrico Gallino discusses Characterization Tools for Evaluating Polymer Powders for Laser Sintering. As additive manufacturing (AM) transitions from the fabrication of prototypes to production of end-use parts, understanding the powder properties required to reliably produce high quality parts is critical. Achieving optimal quality not […]
Powder Flow– An Industrial Perspective on the Need to Turn Art into Science
Find out how industrially relevant powder characterization can optimize your processes. Our guest speaker David Smith, of DJS Process Consulting, brings a 30 year perspective on real world industrial powder handling problems, from raw bulk materials to final packaged products. He presents an industrial perspective on powder flow test methods and scale-up of powder processes, […]
Testing Powders at Elevated Temperatures
Across diverse industries, powders are often handled at elevated temperatures. For example, an additive manufacturing (AM) build chamber may be heated to reduce warpage and thermally induced stress in the finished component, while catalysts routinely operate at substantially elevated temperature to achieve commercially attractive productivity. Pasteurization and dehydration are examples of heat treatments applied to […]
Understanding The Flowability Of Spray Dried Milk Powders Using The FT4 Powder Rheometer®
Introduction Milk powders produced by spray drying are used across the food industry to make productsranging from confectionery and baked goods to soups, sauces, and beverages; they are alsosupplied directly to consumers. The flow properties of these powders define their utility andby extension their value, notably for efficient and effective food processing. Powders that floweasily […]
