Potassium Feldspar (R6182)

K-Feldspar
Potassium 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.
