Nepheline syenite, a non-consisting free slica crystalline rock , is formed of albite , microcline type of feldspar and nepheline mineral. Non-consisting free slica , highalkaline and alumina , high melting capacity and low melting range are idealcharacteristics of nepheline syenite adjusting to the ceramic and glass industry.This means that the mineral nepheline syenite consists higher alumina and alkalinecompared to typical felspar. Nepheline syenite is an important source of silica (%59-60), almina (%20-24 Al2O3) and alkali (% 8-10 Na2O, % 5-7 K2O). Nepheline syenite rockconsists of Nepheline, microcline and albite minerals.Chemically low silica , high alkaline and miner logically non-consisting free silica innepheline syenite composition forms a glassy phase with low viscosity at lowtemperature.Moreover, high alumina in the composition increases the resistance of glassy phasedeformation and low deformation values are obtained despite high alkaline content.Nepheline due to non-consisting free silica has a significant capability of reacting withsilica and resolving.The high alumina and resolving capability of quartz in the composition of nepheline, increases the durability by supporting mullite formation.
