Quartz Powder Manufacturer & Exporter for Ceramic Tiles, Porcelain, Sanitaryware & Glass

Aalok Overseas India is a mine-direct manufacturer and exporter of high-purity Quartz Powder from Rajasthan, India. Established in 1992, we supply low-iron, XRF-verified Quartz Powder in multiple mesh grades for ceramic tiles, porcelain, sanitaryware, glass, paints and construction chemicals, shipped in bulk through Mundra and Kandla ports.

What Is Quartz Powder Used For?

Quartz Powder is finely ground, high-purity crystalline silica (SiO2) used as a raw material across several industries. In ceramics, it supplies the free silica that forms the rigid skeletal structure of the fired body, controls thermal expansion, limits shrinkage and warpage, and helps prevent glaze crazing by matching the thermal expansion of glaze to body.

Because Aalok Overseas mines and processes Quartz Powder directly, buyers get consistent particle size, iron content and whiteness from the pit to the port, without a trader intermediary in between.

Chemical & Physical Specifications

• SiO2 (Silica): 98.5% - 99.5%
• Fe2O3 (Iron Oxide): 0.02% - 0.05%
• Al2O3: 0.2% - 0.6%
• Whiteness (GE): 85 - 92
• Moisture Content: Less than 0.1%

• Mesh Size (PSD): 100 - 500 mesh
• Loss on Ignition (LOI): Less than 0.3%

Mesh Grades We Supply

• 100-150 Mesh (Tile Body Grade): Coarser grind for wall and floor tile body formulations needing controlled porosity and green strength.
• 200 Mesh (Standard Ceramic Grade): The most common grade across vitrified tile bodies and general ceramic formulations.
• 300 Mesh (Porcelain & Sanitaryware Grade): Finer grind for vitreous china and porcelain bodies needing higher fired strength and translucency.
• 400-500 Mesh (Glaze & Glass Grade): Fine, low-iron powder for glaze suspensions, frit batches and specialty glass applications.

Applications by Industry

• Ceramic Floor & Wall Tiles: Free silica backbone in body composition; reduces warpage and controls thermal expansion match with glaze.
• Vitrified & Porcelain Tiles: Higher-purity grades support fine microstructure and mechanical strength during vitrification.
• Sanitaryware (Vitreous China): Low-iron, controlled particle size for whiteness and dimensional stability in basins, WCs and cisterns.
• Glass Manufacturing: High-SiO2, low-iron grades used as a silica source in container, sheet and specialty glass batches.
• Frits & Glazes: Fine mesh grades for glaze suspensions and frit formulations needing consistent silica reactivity.
• Paints, Coatings & Construction Chemicals: Used as a filler and extender in paints, putties, tile adhesives and epoxy formulations.

Quality Assurance & Documentation

Every consignment ships with a batch-specific, XRF-verified Certificate of Analysis reporting SiO2, Fe2O3, Al2O3, whiteness, moisture and particle size distribution. Because Aalok Overseas controls extraction and processing directly, buyers get lot-to-lot traceability back to the source deposit. Mesh size, whiteness targets and iron thresholds can also be customized to match a buyer's existing formulation, with pre-shipment samples available for trial firing.

Frequently Asked Questions

What is Quartz Powder used for in ceramics and tiles?
Quartz Powder supplies free silica (SiO2) to ceramic tile bodies and glazes. It controls thermal expansion, adds fired strength, reduces shrinkage and warpage, and helps prevent glaze crazing by matching body-to-glaze expansion coefficients.

What SiO2 purity does Aalok Overseas Quartz Powder offer?
98.5% to 99.5% SiO2, with low iron oxide (Fe2O3) of 0.02% to 0.05%, suited to white-body tiles, porcelain and sanitaryware where post-fire iron staining must be minimized.

Which mesh sizes are available for export?
100 to 500 mesh (BSS/ASTM). Coarser 100-200 mesh grades suit tile body formulations; finer 300-500 mesh grades suit glaze, sanitaryware and glass applications.

Is Quartz Powder suitable for sanitaryware manufacturing?
Yes. Low-iron, controlled particle size Quartz Powder is a standard raw material in vitreous china bodies, supporting dimensional stability and whiteness in the fired product.

Does Aalok Overseas provide a Certificate of Analysis with shipments?
Yes. Every shipment includes an XRF-verified CoA reporting SiO2, Fe2O3, Al2O3, whiteness, moisture and particle size distribution.

Which ports does Aalok Overseas use to export Quartz Powder?
Primarily Mundra Port and Kandla Port in Gujarat, serving Vietnam, Indonesia, Malaysia, GCC countries, Sri Lanka, Bangladesh and Turkey.

What is the HS Code for Quartz Powder exported from India?
Typically HS Code 2506.10 (Quartz) or 2517.10 depending on grade and processing state. Confirm the exact classification with your customs broker for the specific order.

How is Quartz Powder packaged for export?
25 kg or 50 kg PP/HDPE bags on pallets, or 1-ton jumbo bags, loaded into standard 20ft or 40ft containers, customized to your handling equipment and port requirements.

What is the difference between Quartz Powder and Feldspar in ceramic bodies?
Quartz Powder contributes free silica that forms the rigid skeletal structure of the fired body and controls thermal expansion. Feldspar acts as a flux, lowering vitrification temperature and forming the glass phase that bonds the body. Most formulations use both in balanced proportions.
