The as-synthesized LTA zeolite particles were characterized by powder X-ray Diffraction (XRD) analysis, Scanning Electron Microscopy (SEM), Fourier Transform InfraRed (FT-IR) spectroscopy, Energy Dispersive X-ray (EDX) analysis  and surface area measuring technique of Brunauer, Emmett and Teller (BET). XRD patterns and FT-IR spectra were ascertained the formation of pure crystalline phase of 4A (i.e. LTA) zeolite. SEM micrograph was shown particles size in the range of 60 -170 nm with uniform morphology. The Si /Al ratio of the as-synthesized zeolite nanoparticles was 1.66 with a BET surface area of 421 m2/g.}, keywords = {LTA zeolite,Nanoparticle,hydrothermal synthesis,Controlled crystallization}, url = {https://ijcce.ac.ir/article_6246.html}, eprint = {https://ijcce.ac.ir/article_6246_9037257e0cf859132025d3085884aecc.pdf} }
