About This Product

India's Best High-Whiteness Sodium Feldspar Powder — 200M & 325M for Tiles, Porcelain, Glazes & Sanitaryware

Sodium Feldspar (Albite, NaAlSi₃O₈) — also known as Soda Feldspar or Na-Feldspar — is the essential ceramic flux that drives vitrification, glaze fusion, and glass phase development in tile bodies, porcelain, sanitaryware casting slips, and ceramic glazes. With Na₂O 9–11%, it melts at lower temperatures than potash feldspar (~1050°C onset vs ~1150°C), making it the preferred choice for energy-saving fast-fire wall tile production and transparent glaze formulations worldwide.

Aalok Overseas manufactures and exports high-whiteness sodium feldspar powder in 200 Mesh and 325 Mesh from the finest albite-rich ore deposits of Rajasthan and Gujarat, India. Our ceramic-grade soda feldspar consistently achieves Na₂O 9–11%, Fe₂O₃ below 0.10%, and Hunter Lab whiteness 82–89% — verified by NABL-accredited XRF analysis and laser PSD on every commercial lot.

We supply in 25 kg bags, 50 kg bags, and 1000 kg FIBC jumbo bags and can quote FOB Mundra, FOB Nhava Sheva, CFR Jebel Ali, CFR Dammam, CFR Port Klang, CFR Colombo, CFR Karachi, CFR Chittagong, CFR HCMC and all major regional ports — making us the most convenient supplier for tile factories across GCC, South Asia, and Southeast Asia.

"In a fast-fire monocottura wall tile body, soda feldspar is the single most important raw material. Its Na₂O content directly controls the firing temperature, melt quantity, and vitrification speed. A consistent Na₂O of 9.5–10.5% from Aalok Overseas means you can set your kiln and fire — without adjusting for raw material variation batch after batch."

📌 Buyer Alert — Na₂O Verification: Always verify Na₂O on your COA. A genuine high-quality soda feldspar must show Na₂O minimum 9.0% with K₂O below 2.5%. Any material with Na₂O below 8% is a mixed or contaminated feldspar — it will not perform as sodium feldspar in your ceramic body. Aalok Overseas guarantees minimum Na₂O 9% on every commercial lot, verified by NABL XRF analysis and reported on the COA.

Ceramic Applications

Ceramic & Tile Applications of Sodium Feldspar 200M & 325M

🏺 Fast-Fire Wall Tile (Monocottura)

单次烧成 · كرات أحادية · Monocottura · монокоттура · Tek pişirim · Đơn nung

Soda feldspar is the preferred flux for fast-fire single-cycle wall tile. Its lower melting onset (~1050°C) versus potash feldspar (~1150°C) enables faster firing cycles, reduced kiln dwell time, and significant energy savings. This makes it the economic choice for the GCC, Southeast Asian, and South Asian tile markets where energy cost is a major production variable.

Grade: 200M · Na₂O 9%+ · Fe₂O₃ <0.10% · Whiteness 82%+

⚗️ Transparent & Semi-Transparent Glazes

透明釉 · زجاج شفاف · Glasur · Esmalte transparente · Émail transparent · Effetto vetro

Soda feldspar is the standard flux in transparent, satin, and semi-gloss glaze formulations due to its lower melt viscosity versus potash feldspar. Its fluid melt produces self-levelling, pinhole-free glaze surfaces. At 325M, it dissolves rapidly into the glaze melt at 1050–1150°C — producing the crystal-clear, defect-free transparent glaze layer that premium tile buyers demand.

Grade: 325M · Na₂O 10%+ · Fe₂O₃ <0.08% · Whiteness 85%+

💎 Porcelain Stoneware & Floor Tiles

瓷砖 · بورسيلان · Gres · Porselen · Porcellanato · Gạch porcelain · Gres seramik

In porcelain stoneware body formulations, soda feldspar (typically 30–40% of recipe) works alongside potash feldspar and quartz to develop the glass phase that achieves water absorption below 0.5% at 1180–1220°C. 325M sodium feldspar provides better glass phase distribution and faster densification than coarser material at the same temperature.

Grade: 325M · Na₂O 9%+ · Fe₂O₃ <0.10% · Whiteness 83%+

🚿 Sanitaryware — Casting Slip

卫生洁具 · صحي · Sanitärware · Sanitarios · Appareils sanitaires · Sanitari

Vitreous china sanitaryware casting bodies (WC pans, washbasins) contain 20–35% feldspar total. A blend of soda and potash feldspar is common — the soda feldspar lowers the overall firing temperature and improves fluidity of the glass phase, while potash feldspar provides viscosity control. 325M mesh ensures uniform distribution in the casting slip.

Grade: 325M · Na₂O 9%+ · Fe₂O₃ <0.08% · Whiteness 84%+

🪟 Glass Batch — Na₂O Source

玻璃批料 · دفعة زجاجية · Glasscharge · Vidrio · Verre · Cam kütlesi · Mẻ thủy tinh

In glass batch formulations, albite/soda feldspar simultaneously provides Al₂O₃ (improves chemical durability) and Na₂O (partial replacement for soda ash — cost saving) — making it more economical than adding these oxides separately. Used in container glass, float glass, and fibreglass manufacturing.

Grade: 200M · Na₂O 9%+ · Fe₂O₃ <0.08% for clear glass

🎨 Paints, Coatings & Construction Fillers

涂料 · دهانات · Boya · Pinturas · Peintures · Lacke · Sơn

Soda feldspar powder (200M–325M) is a functional extender in architectural paints, anti-corrosion primers, wall putty, and industrial coatings. Mohs 6–6.5 hardness adds scrub resistance and exterior durability. Chemical inertness ensures compatibility with all binder systems. Competitive pricing vs calcium carbonate with superior hardness.

Grade: 200M–325M · Standard / Premium · Whiteness 78%+

FAQ

Frequently Asked Questions — Sodium Feldspar Powder for Ceramics

QWhy is sodium feldspar preferred over potash feldspar for fast-fire wall tile production?

ASodium feldspar melts at a lower temperature (~1050°C onset) than potash feldspar (~1150°C) because Na⁺ ions are smaller and more mobile than K⁺ ions, making them more effective at disrupting the aluminosilicate glass network at lower temperatures. In fast-fire monocottura wall tile kilns (cycle time 35–50 minutes at 1080–1120°C), this lower melting temperature means more complete vitrification in less time with less energy — directly reducing fuel consumption per square metre of tile produced. Additionally, the lower melt viscosity of Na-feldspar produces more fluid glazes that are self-levelling and pinhole-free.

QShould I use 200 mesh or 325 mesh sodium feldspar for my ceramic application?

A200 Mesh (D50 45–55µm) is standard for most wall tile and floor tile body formulations fired at 1050–1180°C. It provides adequate reactivity, good dimensional stability, and is more economical. 325 Mesh (D50 20–30µm) is preferred for glaze formulations (faster melt, smoother surface), premium porcelain stoneware bodies (denser glass phase, better MOR), sanitaryware casting slips (better suspension stability, more uniform wall thickness), and any application requiring more complete feldspar dissolution at a given temperature. Many tile producers use a blend: 60% 200M + 40% 325M for body formulations, balancing economics with performance.
