Large-scale production of nano-sized LTA-type zeolite particles by beads-milling and recrystallization method were demonstrated. The particles were finely milled, and their crystallinity decreased with increasing milling time. The beads-milled particles retained a zeolitic local structure of Al and Si but cause partial amorphization and loss of gas adsorption ability. Recrystallization recovered the long-range order of the zeolite crystal structure and gas adsorption ability. Smaller beads lead to finer particles and inhibit amorphization of the zeolite.
