agglomerate sintering

Study of the mobility surface area and sintering 155b Polydispersity of Primary Particles in Agglomerates

Tandem differential mobility analysis was used to determine agglomerate mobility diameter by selecting monodisperse agglomerates with the same number of primary particles in the first DMA and subsequently completely sintering the agglomerates in a furnace aerosol reactor The size distribution of the completely sintered particles was measured by an SMPS system which allowed for the AIChE s privacy policy has been updated effective May 25 Learn more Close this message
