At Apex International, we specialize in the export and supply of premium-grade Feldspar, delivering reliable quality and consistent chemical performance to global industries. Our feldspar is sourced from carefully evaluated mineral deposits and processed in advanced facilities under stringent quality control systems to ensure uniformity, purity, and technical accuracy.
Feldspar plays a critical role as a natural flux in ceramic and glass manufacturing. With controlled alumina and alkali content, our material enhances vitrification, improves mechanical strength, and optimizes melting behavior. Through modern crushing, grinding, magnetic separation, and grading processes, we maintain precise particle size distribution and minimal contamination levels, meeting exact buyer specifications.
Product Highlights:
Industrial Applications:
Our feldspar is widely used across diverse sectors, including:AVAILABLE FELDSPAR VARIETIES:
1. Potassium Feldspar (K-Feldspar / Potash Feldspar):
Potassium Feldspar is rich in potassium oxide (K₂O) and is highly valued in ceramic and glass formulations. It promotes strong vitrification, improves translucency, and enhances finished product strength.
Typical Chemical Composition:
| Na₂O (Sodium Oxide) | 2 – 4 % |
| K₂O (Potassium Oxide) | 10 – 14 % |
| Al₂O₃ (Aluminium Oxide) | 17 – 19 % |
| SiO₂ (Silicon Dioxide) | 65 – 70 % |
| Fe₂O₃ (Iron Oxide) | 0.05 – 0.3 % |
Technical Advantages:
Common Uses:
Ceramic tiles, sanitaryware, porcelain, glass production, and ceramic glazes.
2. Sodium Feldspar (Na-Feldspar / Albite Feldspar):
Sodium Feldspar contains higher sodium oxide (Na₂O) content, offering faster melting characteristics and improved glass clarity. It is particularly suitable for industries requiring lower firing temperatures and enhanced bonding.
Typical Chemical Composition:
| Na₂O (Sodium Oxide) | 8 – 12 % |
| K₂O (Potassium Oxide) | 0.5 – 3 % |
| Al₂O₃ (Aluminium Oxide) | 18 – 20 % |
| SiO₂ (Silicon Dioxide) | 68 – 72 % |
| Fe₂O₃ (Iron Oxide) | 0.05 – 0.3 % |
Technical Advantages:
Common Uses:
Glass manufacturing, ceramic bodies, frits, enamels and specialty applications.
3. Feldspar Export Quality:
Rajasthan is one of the leading sources of feldspar minerals used in ceramics and glass industries. Many suppliers provide mixed feldspar suitable for export with balanced alkali composition and low iron content.
Typical Chemical Composition:
| K₂O (Potassium Oxide) + Na₂O (Sodium Oxide) combined | 10 – 15 % |
| Fe₂O₃ (Iron Oxide) | < 0.15 % |
| SiO₂ (Silicon Dioxide) | 65 – 70 % |
Advantages:
Applications:
Ceramic bodies, vitrified tiles, sanitaryware, glass manufacturing, and engineered stone.
