In　order　to　understand　the　growth　behaviors　of　the　aluminosilicate　species　in　the　initial　hydrothermal　process　and　thereafter　synthesis　of　clinoptilolites　with　high　purity,　the　physicochemical　characteristics　of　the　aluminosilicate　nanoparticles　were　elucidated　by　small　angle　X-ray　scattering　(SAXS)　and　X-ray　diffraction　(XRD)　patterns,　scanning　electron　microscopy　(SEM)　images,　Ultra-Violet　Raman　(UV-Raman)　and　Fourier　transform　infrared　(FT-IR)　spectra.　The　results　demonstrated　that　the　aluminosilicate　nanoparticles　presented　the　first　decreased　surface　fractal　(D-s)　values　and　then　an　increased　D-s　values　in　the　initial　reaction　time　of　before　120　h.　After　that,　the　fractal　transformations　from　D-s　to　mass　fractal　(D-m)　occurred　with　the　extensions　of　reaction　time　(120-144　h),　but　the　decreased　D-m　values　appeared　after　144　h.　Therefore,　their　growth　mechanisms　from　uniform　dispersions　to　aggregation,　and　even　assembly　were　proposed.
