Why Do BET Results Change With Degassing and Adsorptive Gas?
A BET surface area reflects how the sample was [...]
Micronization by Jet Milling: How Classification, Milling Intensity, and Time Change Surface Properties
Jet milling micronization reduces particle size through particle-particle impact controlled by classifier wheel speed and feed rate. Pushing the cut point lower can raise amorphous surface content and hygroscopicity in ways a passing PSD result will not reveal. This guide covers the mechanism and the tests that actually diagnose a changed lot.
X-ray Micro-CT for Powder Pore Networks: What It Adds Beyond Gas Pycnometry and BET Surface Area
Gas pycnometry and BET surface area each report a single number. X-ray micro-CT builds a three-dimensional map of the pore network, showing connectivity, tortuosity, and closed porosity that single-value tests cannot resolve, within real resolution and sample-size limits.
