Hydroxy sodalite (HS) particles were synthesized hydrothermally at 90°C for 10 h in the presence of cetyltrimethylammonium bromide (CTAB) and other aqua‐based precursor materials like sodium aluminate, sodium metasilicate, and water. Crystalline phases and microstructures of the synthesized particles were studied by X‐ray diffraction and field emission scanning electron microscopy, respectively. The effect of CTAB concentrations on the crystallinity and morphology of the synthesized particles was investigated. Thread‐ball like HS particles along with some cube‐shaped zeolite A were obtained in the presence of 0–0.5 mM CTAB while flower‐like HS particles were observed in the presence of 1–5 mM of CTAB concentrations. With increase in CTAB concentration, HS phase increased significantly, and phase pure HS particles resulted for 3 and 5 mM of CTAB concentrations. A mechanism for the formation of flower‐like HS particles was also proposed.
