Potash Feldspar Suppliers in India
Potash feldspar melts at approximately 1200°C, producing a more viscous melt than sodium feldspar and creating a crystalline phase called leucite that contributes to opacity. This potassium-based mineral promotes vitrification in clay bodies, transforming materials into glass during firing at elevated temperature. As leading potash feldspar suppliers in India, we provide premium-grade material for demanding applications.
- Viscous Glass Formation
- Durability Enhancement
- Optimized Vitrification
- Enhanced Translucency
Why We Are a,
Leading Potash Feldspar Manufacturer in India
Expolica Ceramics extracts premium potash feldspar from our five specialized mines, delivering high potassium content material with consistent K2O levels. Our rigorous processing ensures superior vitrification properties for tiles, sanitaryware, and porcelain manufacturing nationwide.
- High Potassium Oxide Content: Our potash feldspar maintains K2O content between 10-12%, significantly higher than industry averages. This elevated potassium level provides stronger fluxing action during firing, creating denser ceramic bodies with improved mechanical strength.
- Controlled Alumina-Silica Ratio: We monitor the Al2O3 to SiO2 ratio closely, maintaining it between 1:6 to 1:7 for optimal glass formation. This balanced ratio ensures proper viscosity during melting, preventing excessive flow that causes warping or insufficient vitrification.
- Minimal Color-Causing Impurities: Iron and titanium oxide levels remain below 0.2% in our potash feldspar through selective mining and magnetic separation. Low impurity content translates to brighter fired colors and reduced staining issues.
- Multiple Particle Size : Available in 40 mesh for dry pressing, 100 mesh for general applications, and 200 mesh for fine porcelain work. Particle size directly affects melting rate and glass distribution throughout your ceramic body.
- Leucite Phase Development : Our potash feldspar's specific composition promotes controlled leucite crystal formation during cooling, contributing to opacity and thermal shock resistance. This crystalline phase strengthens the final product and creates desirable matte surface characteristics.
- Geographic Proximity : With mines distributed across the state, we reduce transportation distances and costs for regional manufacturers. Shorter supply chains mean fresher material with less handling degradation and faster response to urgent orders.
