FELDSPAR SOLUTIONS
High-Performance Feldspar Solutions for Advanced Ceramics & Glass
Engineered feldspar grades tailored for tiles, sanitaryware, tableware, technical ceramics and glass applications, optimized for consistency, whiteness and thermal stability.
Rio Clays delivers precisely engineered feldspar for demanding industrial processes. Our controlled particle size distribution, low impurity profile and stable chemistry help manufacturers improve firing performance, surface quality and production efficiency.
Tiles & Floorings
Optimized for rapid firing and dimensional stability. Enhances glaze fit, surface smoothness and strength. Consistent PSD for reliable pressing and reduced defects.
Technical Ceramics & Insulators
Tailored alkali content for electrical insulation performance. Supports dense microstructure and high mechanical strength. Consistent behavior in high-temperature duty cycles.
Feldspar Solutions by Application
We design feldspar grades around your firing curve, body formulation and line constraints. From mass-market tiles to specialty technical ceramics, our products support stable, repeatable output at scale.
Sanitaryware
High whiteness and low iron for premium visual quality. Supports low-porosity, high-strength bodies. Stable shrinkage behavior for complex forms.
Glass & Frits
Reliable fluxing action for energy-efficient melting. Helps improve clarity, color control and durability. Compatible with a wide range of glass formulations.
Tableware & Porcelain
Controlled fusion to improve translucency and gloss. Uniform firing behavior for tight tolerances. Clean chemistry for food-contact safety requirements.
Custom Formulations
Lab support for body trials and line optimization. Matching to your existing specification or target properties. Long-term supply planning for large-volume plants.
Proven Feldspar Performance in Production
Our feldspar grades are integrated into large-scale plants across tiles, sanitaryware, tableware and technical ceramics. Here are a few representative outcomes.
Tile Manufacturer (Asia)
Challenge: High rejection due to warping and glaze defects at fast-fire temperatures.
Solution: Transitioned to a Rio Clays feldspar grade with optimized PSD and controlled alkali content.
Result: 18–22% reduction in firing defects; more stable glaze fit and surface finish; smoother press performance with fewer cracks.
Sanitaryware Producer
Challenge: Inconsistent whiteness and pinholes in high-end bathroom fixtures.
Solution: Introduced a low-impurity feldspar blend tuned to their body recipe and firing profile.
Result: Noticeable improvement in whiteness and gloss; reduced re-firing and rework; more predictable casting and drying behavior.
Technical Ceramics Supplier
Challenge: Tight dimensional tolerances and mechanical strength requirements for electrical insulators.
Solution: Application-driven feldspar selection and joint lab trials on pilot batches.
Result: Stable shrinkage across batches; improved strength and reliability in service; simplified quality control through narrow property variation.
