Potash Feldspar

Brindavan Minerals supplies high-quality Potash Feldspar, a key raw material widely used in ceramics, glass, and tiles manufacturing. Carefully mined and processed, our Potash feldspar is valued for its high alumina content, K₂O and SiO₂, ensuring superior product performance and aesthetic appeal.

Our Potash feldspar exhibits outstanding fluxing properties at lower firing temperatures, which improves strength, enhances surface finish, and stabilizes the glass phase by controlling melt viscosity and temperature. This results in more durable and consistent end products.

We serve both domestic and global markets, offering custom particle sizes and packaging options to meet varied manufacturing needs. Whether you're in ceramics, glass, or enamel production, our feldspar supports optimal process efficiency and product quality.

Product Overview

Potash Feldspar (K₂O·Al₂O₃·SiO₂) is a vital fluxing agent in the manufacture of ceramics, glass, tiles, and sanitaryware. Rich in potassium and alumina, it contributes to improved strength, durability, and gloss in finished products. Its high potassium content enhances vitrification and lowers firing temperatures, making it ideal for high-performance ceramic and glass formulations.
