Method for Measuring Apparent Densities of Zeolite Nanopowders using Piezoelectric Energy

This study investigated factors influencing the flowability of zeolite using three types of commercial zeolites with low flowability – Zeolite-beta, Zeolite-Y, and ZSM-5 - and manufactured a device applying piezoelectric energy to measure their apparent density. Zeolite properties such as flow function (FF) and cohesion by Powder Rheometer, elemental analysis by XRF, specific surface area, pore characteristics, and shape of zeolite particles by FE-SEM, average particle size and size distribution by particle size analyzer were analyzed. Low flowability zeolite could pass through a mesh hole moved by piezoelectric energy. The apparent density measured by the device applying piezoelectric energy was found to be more uniform with a smaller standard deviation than existing density measurement equipment.
