Application:
In addition to industrial raw materials, more than 30% of sodium feldspar mineral is used in ceramic industry, and it is also widely used in other industries such as chemical industry.
1, glass solvent:
Feldspar is one of the main ingredients of the glass. The content of alumina is high, while content of iron is low, it can reduce the amount of alkali. In addition, after the dissolution of feldspar into glass, the process is slow and small, which can prevent the formation of crystal in the process of glass.
2, ceramic body ingredients:
in the firing of feldspar can be barren of raw materials, reduce green body drying shrinkage and deformation, improve the drying performance, shorten the drying time, when firing can be as flux filling in blank, the blank compact and reduce the gap, but also improve the transparency of the green body.
3, ceramic glaze glaze:
to become soft, reduce the melting temperature of glaze.
4, enamel raw materials:
the main use of feldspar and other mineral raw materials blending into enamel, mixing amount is usually 20 - 30% above.
5, other: potassium, sodium feldspar can also be used as a raw material for the production of chemical fertilizer.
