Cohesion
Cohesion refers to the force that holds particles of the same material together, influencing the behavior of powders and bulk solids. This property plays a critical role in industries like pharmaceuticals, food, and chemicals, where material flowability, packing density, and processing efficiency are directly impacted.
On this page, explore the principles of cohesion, its effects on material performance, and strategies to optimize particle behavior for improved industrial applications.

Hausner Ratio and Carr Index: What the Numbers Tell You and Where They Break Down
Both the Hausner Ratio and Carr Index reduce bulk and tapped density to a single number. The mechanism behind that number, whether aeration, particle shape, or surface cohesion, determines whether it supports a process decision or actively misleads one.
The Dictators of Powder Behavior: A practical guide to powder behavior control in production
Powder behavior control starts with fifteen core factors. Tune particle size, shape, surface energy, moisture, charge, and environment. Use ring shear, Hausner ratio, and DEM insights to design predictable flow, mixing, and compaction. Table of contents Powder behavior control starts with particle size, it sets [...]
Catalytic Hot Spots in Powders: Small Regions, Big Consequences
Catalytic hot spots in powders often determine stability. Detect them early with targeted screening. Reduce mobility, limit contact, and lower energy to control risk. Confirm improvements with defined stress holds and retests. Why Catalytic Hot Spots in Powders Matter Powders may look uniform. Their chemistry rarely is. [...]
Dry Electrode Battery Manufacturing: Powder Rules for Modern Factories
Dry electrode battery manufacturing demands tighter powder control. Flow, moisture, and morphology define stability, yield, and cost. Table of contents Dry electrode battery manufacturing is no longer a niche R&D ambition. Instead, it is rapidly moving into large-scale production. The attraction is clear: lower costs, [...]
Energetic States and Chemical Dynamics in Powder Systems
Energetic states in powder systems depend on more than material composition. Internal coherence, entropy gradients, and surface energy determine how powders respond to mechanical, thermal, and environmental stress. Controlling these energetic variables enables predictive processing, coating performance, and long-term stability. Table of contents Introduction: From [...]
