Sodium Feldspar · Soda Feldspar
Albite Feldspar
https://www.feldsparindia.com/sodium-feldspar.htm
India's trusted supplier & exporter of high-purity Sodium Feldspar (Albite / Soda Feldspar) for ceramics, glass, tiles, sanitaryware, paints & specialty industries worldwide.
What is Sodium Feldspar? (सोडियम फेल्डस्पार | Feldspato Sódico | Natriumfeldspat)
Sodium Feldspar — scientifically known as Albite (NaAlSi₃O₈) — is one of the most industrially vital feldspar minerals on earth. Aalok Overseas India is a leading manufacturer, processor, and bulk exporter of this critical raw material, sourced from the mineral-rich belts of Rajasthan and neighbouring states.
Feldspar is the most abundant mineral group in the Earth's crust, and Sodium Feldspar (Soda Feldspar) is the sodium-rich end member of the plagioclase feldspar series. With a chemical formula of NaAlSi₃O₈, Albite is characterized by its high alumina content, low iron oxide, consistent sodium oxide (Na₂O) levels, and a controlled silica-to-alumina ratio — making it indispensable in dozens of industrial applications.
At Aalok Overseas India, we mine, beneficiate, grind, and supply premium-grade Sodium Feldspar in various mesh sizes and grades — from raw lumps to ultra-fine powder — tailored precisely to your industry's technical requirements.
