Feldspar – Essential Mineral for Ceramic and Glass Industries
Widely Used in Tiles, Glass, Enamels & Industrial Manufacturing
High Quality Feldspar for Ceramic and Glass Production
Feldspar is a group of rock-forming minerals that play an important role in the manufacturing of ceramics and glass products. It acts as a fluxing agent that reduces the melting temperature of raw materials during production processes.
Because of its chemical composition and melting characteristics, feldspar improves the strength, hardness, and durability of finished ceramic and glass products.

Versatility Across Industries
| Industry | Primary Use | Key Benefit |
|---|---|---|
| Ceramics | Vitrification Agent | Acts as a flux to bind particles into a dense, durable, and non-porous ceramic body. |
| Glassmaking | Alumina Source | Improves the hardness, durability, and chemical resistance of glass containers and fiber. |
| Glazes & Enamels | Glass-forming Agent | Ensures a smooth, glossy, and transparent finish on tiles, sanitaryware, and tableware. |
| Abrasives | Binder | Used as a mild abrasive and binder in grinding wheels and scouring soaps. |
| Fillers | Paint & Rubber | Provides excellent chemical resistance and durability in high-performance coatings. |
Pro Tip: In Sanitaryware and Tile manufacturing, the balance between Potash and Soda Feldspar is key. Using a “blend” allows you to lower the firing temperature (saving energy) without sacrificing the “green strength” of the piece before it enters the kiln.
Applications
Why Choose Asteroid Microns Feldspar?
- Low Iron Content (Fe2O3): We maintain strict quality control to ensure ultra-low iron levels, preventing unwanted “yellowing” or “spotting” in high-end porcelain and clear glass.
- Controlled Particle Size: Available in various forms, from coarse grains to micronized 500-mesh powders, ensuring uniform melting rates in your furnace.
- High Alumina Delivery: Our feldspar provides a consistent source of Al2O3, which enhances the thermal shock resistance of your final products.
- Consistency in Chemistry: We blend different mine ores to ensure that the Na2O and K2O ratios remain constant batch after batch, so you don’t have to adjust your firing curves.
Available Gradations
- Lumps: 1 inch to 10 inches (For large-scale industrial grinding)
- Grains: 30/80 Mesh, 40/100 Mesh (For glass and abrasive industries)
- Powders: 200 Mesh, 300 Mesh, 500 Mesh (For fine ceramics and glazes)
