Sodium feldspar, also known as soda feldspar or albite, is a member of the feldspar mineral group that contains a high percentage of sodium. Sodium feldspar powder is a feldspar product with a high concentration of sodium oxide (Na₂O), typically sourced from sodium-rich minerals like albite and oligoclase. This powder is commonly used in the ceramics industry, particularly for producing porcelain and sanitary ware. It aids in reducing the melting point of ceramic materials, improving their plasticity, and enhancing the quality of glazes. Additionally, soda feldspar powder is also employed in the production of glass, enamel, and other materials that require a high alkali content. Sodium feldspar is more commonly used in the glass industry, while potassium feldspar is favored in ceramics and glazes due to its higher melting point.
