The polymorphs of NaAlSiO4, namely low-carnegieite, nepheline and high-carnegieite, are prepared through gel to crystallite conversion. As-prepared compound has the composition, NaAlSiO4. 1 . 5H(2)O (nepheline hydrate), and acts as a precursor for low-carnegieite. The latter is obtained by decomposing the nepheline hydrate at 800 degrees C, which has an orthorhombic structure and the X-ray diffraction pattern is indexed based on the space group Pmaa. Low-carnegieite is metastable and can be rehydrated to form nepheline hydrate. At 950 degrees C, low-carnegieite transforms to nepheline which, in turn, transforms to high-carnegieite at 1300 degrees C. Low-carnegieite and nepheline do not show any luminescence when doped with Fe3+, whereas the...
