A sodium gallium silicate probably NaGaSiO_4 has been synthesized by high temperature solvent growth. This compound is probably a structural analogue of nepheline. It is hexagonal, possibly P6 a=8.63A c=8.35A. The crystals are clear, colorless, well-formed hexagonal prisms, devoid of cleavage, occasionally showing cruciform twins. The crystals are uniaxial(-) with indic es of refraction ?=1.540, ?=1.521.
