Improving Nanosilica Fluidization by Premixing with Geldart A and B Particles: A Detailed Region-Wise Study [PDF]

Nanomaterials
Ultrafine nanosilica exhibits a strong tendency to form agglomerates, with sizes often several orders of magnitude larger than the primary particles. This agglomeration severely impairs its effectiveness in fluidization and other applications requiring ...
