Nepheline syenite, a non-consisting free silica crystalline rock, is formed of albite, microcline type of feldspar and nepheline mineral. Non-consisting free silica ,high alkaline and alumina , high melting capacity and low melting range are ideal characteristics of nepheline syenite adjusting to the ceramic and glass industry. This means that the mineral nepheline syenite consists higher. Nepheline is characteristic of some alkali-rich Si-poor igneous rocks, both plutonic and volcanic (e.g. syenite, foidite, and phonolite). It is often associated with many minerals such as K-feldspar, Na-rich plagioclase, biotite, amphibole, zircon, and/or pyroxene.
