A key fluxing mineral essential to glass, ceramics, and advanced industrial applications. Precisely graded for consistent alkali content and low iron impurity.
Feldspar is the most abundant mineral group in the Earth's crust and a critical raw material in glass and ceramic manufacturing. As a flux, it lowers the melting temperature of silica, enabling energy-efficient production of glass, ceramic bodies, and glazes.
A.N. Enterprises supplies three distinct feldspar grades — sodium feldspar, potash feldspar, and crystalline feldspar — each processed to deliver precise alkali ratios and exceptionally low iron content for demanding industrial applications.
Our feldspar products are sourced from premium deposits, uniformly ground, and rigorously tested to ensure batch-to-batch consistency in chemical composition and particle size distribution.
Three feldspar grades engineered for specific industrial requirements, each with tightly controlled chemistry and consistent particle size.
High-sodium variety preferred for glass manufacturing where soda content drives the fluxing action. Delivers excellent melt fluidity and glass homogeneity.
High-potassium variety ideal for ceramic bodies and glazes. Provides a wider vitrification range and superior thermal stability during firing.
Premium crystalline grade with balanced alkali content for specialty applications requiring high brightness and ultra-low iron contamination.
Feldspar is indispensable across glass, ceramic, and advanced manufacturing sectors, serving as a primary flux and functional filler.
Sodium feldspar is a principal ingredient in soda-lime glass production, including container glass, flat glass, and specialty glass. It supplies alumina and alkali oxides that lower the melting temperature of silica, improve glass workability, and enhance the chemical durability of the final product.
Potash feldspar is the preferred flux in ceramic glazes and frit formulations. It promotes smooth, glass-like surfaces with excellent gloss and chemical resistance. The high potassium content provides a wider firing range, making it forgiving in kiln temperature variations.
In whiteware and sanitaryware manufacturing, feldspar acts as the primary flux in the triaxial body composition alongside quartz and clay. It controls the vitrification process, developing the translucency, strength, and low porosity essential for tableware, sanitaryware, and electrical porcelain.
Floor and wall tile bodies rely on feldspar as a flux to achieve the required degree of vitrification during firing. It enables densification at lower temperatures, reducing energy costs while delivering tiles with superior mechanical strength and water absorption properties.
Feldspar is used in the coating of welding electrodes where it serves as a slag-forming flux. It creates a protective shield over the weld pool, preventing oxidation and ensuring clean, strong welds in structural and industrial welding applications.
In bonded abrasive manufacturing, feldspar functions as a ceramic bond material that holds abrasive grains together. Its controlled melting behaviour creates a strong yet brittle bond matrix ideal for grinding wheels and cutting discs used in metalworking.
Every batch of feldspar is rigorously tested to ensure it meets the precise chemical and physical specifications demanded by our customers.
Fe₂O₃ is held below 0.1% across all grades, ensuring optical clarity in glass and bright white finishes in ceramic applications. Iron removal is a critical step in our processing.
Sodium and potassium oxide levels are tightly controlled within specified ranges, ensuring predictable fluxing behaviour and repeatable results in every production cycle.
Available in 200 to 500 mesh grades with consistent particle size distribution. Uniform grading ensures homogeneous dispersion in batch formulations and predictable melt behaviour.
Every batch undergoes X-ray fluorescence analysis for complete chemical characterization, verifying alkali content, silica, alumina, and trace element levels against specifications.
Our feldspar is sourced from carefully selected deposits known for their mineralogical consistency, ensuring a reliable supply of high-quality raw material year-round.
All products are packaged in moisture-resistant bags and shipped with complete certificates of analysis documenting chemical composition, mesh size, and moisture content.
Let our team help you select the right feldspar grade and mesh size for your glass, ceramic, or industrial formulation.
