Sodium Feldspar (R6202)

Sodium feldspar; It is classified according to Na2O, Fe2O3 and TiO2 content.
Sodium feldspar, which is used as a sintering trigger especially in the ceramic and glass industry, is also used as a filling material in the paint, plastic and rubber industries in fine grain sizes.
While sodium feldspar from the alumina silicate family exhibits melting behavior at low temperatures in ceramic bodies with the Na2O it contains, it also provides chemical resistance and sintering stability with Al2O3.

Potassium and Sodium Feldspar
They belong to the group of alkali oxides.
They are used as a flux in glazes.
They enter the body as feldspars.
Expansion coefficients are high.
Sodium feldspar is the oxide with the highest coefficient of thermal expansion among all basic oxides.
High Expansion Coefficient causes glaze cracks.
Potassium feldspar is a more commonly used flux.
They are brighter and more durable than soda.
Its viscosity is low.
Al2O3, ZnO2, BaO can be added to increase their viscosity.
Since all salts of potassium and sodium feldspars are soluble in water (soda, potash, etc.), they are used in glazes only after they are fritized.
