Soda Feldspar Suppliers
Soda feldspar acts as an exceptional fluxing agent that lowers the melting temperature of ceramic raw materials, promoting vitrification during firing and leading to enhanced strength, density, and mechanical properties. As trusted soda feldspar suppliers, Expolica Ceramics provides premium-grade material for diverse applications.
- Superior Fluxing Action
- Enhanced Glossiness
- Lower Melting Point
- Chemical Stability
Expolica as a
Soda Feldspar Manufacturers for Ceramic
Expolica Ceramics supplies premium soda feldspar extracted from mineral-rich deposits across our five mines. Our consistent alkali content, controlled particle sizing, and reliable delivery schedules support ceramic manufacturers achieving superior vitrification and product quality.
- Verified Sodium Oxide Content: Our soda feldspar maintains Na2O content between 6-8%, verified through X-ray fluorescence analysis at our laboratory. This consistent alkali level ensures predictable fluxing behavior during firing.
- Low Iron Content : We selectively mine feldspar veins with iron oxide below 0.15%, critical for achieving bright white ceramic bodies. Lower iron means less discoloration after firing and reduced need for expensive opacifiers.
- Optimized Mesh Sizes :Available in 100 mesh, 200 mesh, and 300 mesh grades to match your processing equipment. Coarser grades suit dry pressing operations, while finer meshes integrate better in slip casting formulations.
- Controlled Melting Temperature Range: Our soda feldspar melts progressively between 1150-1200°C, creating uniform glass phase formation throughout the ceramic body. This controlled melting prevents localized over-firing or under-vitrification issues.
- Quarterly Quality Audits : Independent laboratories conduct quarterly compositional analysis of our soda feldspar reserves. We maintain comprehensive quality records including chemical composition, loss of ignition.
- Flexible Order Quantities: We accommodate orders from 10-ton trial quantities to 500-ton monthly contracts. Our warehouse network across Gujarat and neighboring states enables quick replenishment without forcing you to maintain excessive inventory.
