What is feldspar ?
Feldspar is a naturally occurring aluminosilicate mineral widely used in industrial applications. It acts as a fluxing agent in ceramic and glass manufacturing, reducing the melting temperature of mixtures and improving the mechanical strength, durability, and surface smoothness of finished products.
Feldspar is available in two main types: potassium feldspar and sodium feldspar, supplied in lump and powder forms to meet diverse industrial needs.

Frequently Ask
Questions
Feldspar is a group of naturally occurring rock-forming minerals composed mainly of aluminum silicates of potassium, sodium, and calcium. Feldspar minerals are widely used in industrial applications such as ceramics, glass, and manufacturing due to their fluxing properties and high melting points.
Feldspar does not have a single chemical formula because it includes several related minerals. Common feldspar formulas include:
- KAlSi₃O₈ (potassium feldspar)
- NaAlSi₃O₈ (sodium feldspar)
- CaAl₂Si₂O₈ (calcium feldspar)
These represent the main feldspar mineral compositions.
The main types of feldspar are:
- Potassium Feldspar (K-Feldspar)
- Sodium Feldspar (Na-Feldspar)
- Calcium Feldspar (Plagioclase Feldspar)
These feldspar types are classified based on their chemical composition and are widely used in industrial manufacturing.
Feldspar is commonly used across multiple industries due to its role as a flux and performance enhancer. Major applications include:
- Ceramics & Tiles - Improves strength, durability, and surface finish
- Glass Manufacturing - Enhances transparency and melting efficiency
- Sanitaryware - Provides smooth texture and structural stability
- Paints & Coatings - Acts as a functional filler
- Plastics & Rubber - Improves rigidity and thermal resistance
Feldspar is widely used in industrial manufacturing when handled according to standard safety practices. Appropriate dust control and handling measures are recommended during processing and use.
Feldspar is typically supplied in bulk or packaged form based on order requirements. Supply depends on quantity, industry usage, and logistics.
Feldspar is processed through crushing, grinding, washing, and quality testing to achieve the required purity, particle size, and consistency for industrial applications.
