The　yarn-like　spherical　aluminosilicates　materials　were　hydrothermal　synthesized　using　sodium　aluminate,　aluminum　sulfate　as　the　aluminum　source　and　sodium　silicate　as　the　silicon　source.　The　samples　were　characterized　by　XRD,　SEM　and　29Si-NMR,　and　the　results　indicated　that　the　obtained　aluminosilicates　materials　presented　yarn　spherical　morphology,　and　its　particle　size　was　about　4　μm.　By　adding　surfactant　Twen-20　in　the　reactant　mixture,　the　particle　size　of　the　aluminosilicates　materials　could　be　adjusted　to　2-4　μm.
