NEPHELINE PRODUCT SPECIFICATIONS

 Nepheline is a feldspathoid mineral composed of sodium and potassium aluminosilicates, typically found in silica-deficient igneous rocks. Its low silica and high alkali content make it an excellent flux in glass and ceramic production, where it reduces melting temperatures and improves product strength. Nepheline is also used in fiberglass, glazes, and industrial fillers, offering a cost-effective alternative to feldspar with lower iron content and better thermal behavior. Its granular or crystalline form is easy to process, making it a versatile material across multiple manufacturing sectors.
