ABSTRACT: Nepheline syenite is a siliciously poor syenitic rock composed of nepheline, sodium and alcaline feldspars.Although it is wide spread on the earth, the nepheline deposits that have economic value are limited. Commerciallyspeaking, nepheline syenite contains at least 20% nepheline and 60% feldspar. Such economic deposits are in Russia,Canada, Norway, Brazil, China and Turkey. Main uses of nepheline syenite are glass and ceramic industries. It isa source of alumina (Al2O3) and plays a role of melting products such as sanitary ware, porcelain, tile, glass andfiberglass. Because of the numerous advantages on ceramic and glass products, its consumption is high in Asia,Europe and America. In this review, characteristics of nepheline syenite, its formation, production and consumption,usage areas and technology are given
