High-dose powders are critical for treating lung infections or systemic diseases where large amounts of medication must reach the deep lungs. Delivered doses ≥is greater than or equal to Challenges: Fine particles (
In blasting operations, the refers to the amount of explosive (kg) needed to fracture a unit volume of rock.
5 µm) have high cohesion forces, causing agglomeration and poor flow. High Powder
Required for smooth, even flow and better packing.
In additive manufacturing (3D printing) and powder metallurgy, the focus is on achieving and managing high flow dynamics . High Powder Flow Dynamics: High-dose powders are critical for treating lung infections
Achieved by mixing different particle sizes (e.g., trimodal distributions) to fill voids.
Dispersibility, aerodynamic size (ideally 1–3 µm), and aerosolization stability. 🏗️ Manufacturing: High Flow & Density Required for smooth, even flow and better packing
Heat fusion (sintering) or compression transforms "green parts" into hardened solids. Mining: High Powder Factor
