The nepheline syenite can be used in float glass, container glass, fibre glass, opal glass, sheet glass, electrical glass and tableware glass. Nepheline syenite provides necessary additions of alumina and alkali in the glass batch. It has low in silica and contains no free quartz. It also has a favorable ratio of sodium oxide to potassium oxide of 2: 1. Nepheline syenite makes glass batches to have lower viscosity and easier workability compared with potash feldspar. Its high alumina and alkalis content also makes it so suitable for the glass manufacturing.
1. The content of potassium and sodium is high in nepheline syenite, and it can partly replace the soda ash in glass batches.
2. The characteristic of foidal minerals are they will not intergrow with quartz. They can decrease the melting temperature with reaction between nepheline syenite and quartz in glass furnace. The melting temperature would be 40° c lowered than feldspar.
3. The content of al2o3 is high and the content of sio2 is low in nepheline syenite. So it can save the cost of transportation of al2o3.
4. It can decrease the content of fe2o3 in glass.
