nepheline sand

K50 is one model of our nepheline sand .It is carefully selected from high-quality of the biggest original ore by the way of water-washing repeatedly and many times of getting rid of iron by Chiron mining.The whole process is running under strictly quality control management and rigorous supervision test. In glass industry, it’s mainly used in the manufacture of glass, flat glass, milky white glass, glass block and so on . In ceramic industry, it is widely used in ceramic glaze billet, In ceramic glaze billet, using nepheline syenite instead of part or all of feldspar, will significantly reduce the sintering temperature of the porcelain , expand the scope of sintering, reduce low fever into contraction. In the glaze materials, using right amount of nepheline syenite replacing some feldspar can increase the glaze coefficient of expansion.
