Potassium Feldspar

At EarthCore Minerals, we offer high-purity Potassium Feldspar that serves as a vital fluxing agent across various industries. Known for its rich potassium content (K₂O) and high alumina-silicate structure, Potassium Feldspar is extensively used in the manufacturing of ceramic tiles, sanitaryware, tableware, and glass.

Extracted directly from our own mines in Rajasthan and processed in technologically advanced plants, our material meets strict quality and consistency standards. Whether in powdered, grit, or lump form, our K-Feldspar supports optimal melting behavior, lowering firing temperatures and enhancing the mechanical and aesthetic quality of finished products.


Why Choose Earth Core’s Potassium Feldspar?

Mine-to-Plant Control: Our in-house extraction, beneficiation, and micronizing processes ensure total traceability and uniformity in every batch.

Purity Assured: Advanced magnetic separation and color sorting technology help us deliver material with very low Fe₂O₃ and TiO₂ content.

Customizable Grades: We can adjust the K₂O-to-Na₂O ratio, whiteness, and particle size distribution as per your kiln or process requirements.

Flexible Delivery: Available in 25 kg bags, 1 MT jumbo bags, or loose bulk shipments—delivered globally via efficient export logistics.

Applications

Ceramics Industry

Ceramics Industry

Feldspar notably strengthens both the chemical integrity and visual clarity of glazes and ceramic forms. As a major component, it boosts the lifespan and visual charm of ceramic items and adds to their durability and resistance to damage. The presence of feldspar promotes the development of clean surfaces with high quality and facilitates the efficient combination of materials when ceramics are fired.

Glass Industry

Glass Industry

By lowering quartz's melting temperature it improves production flow and encourages the formation of consistent glass. This feature is significant in the production of multiple glass varieties such as standard containers and enhanced glass for particular applications.

Paint and Coating Industry

Paint and Coating Industry

In coatings and paints feldspar boosts their strength and longevity. This quality improves coating resilience and extended lifespan by withstanding harsh weather. As a filler that boosts performance without expensive components, feldspar minimizes production costs in the coatings sector.

Electronic Industry

Electronic Industry

Feldspar of high purity has applications in the electronics industry for the creation of insulating components and the manufacture of efficient electronic ceramics. Owing to its stability and ability to insulate it works perfectly in electronic devices such as capacitors and resistors. Feldspar plays a crucial role in improving the reliability and functionality of electronic equipment stressing its relevance in today's technology.
