At Apex International, we specialize in the export and supply of premium-grade Kaolin Clay, delivering superior whiteness, consistent chemical composition, and dependable performance to global industries. Our kaolin is sourced from carefully selected mineral deposits and processed in advanced facilities under stringent quality control systems to ensure high purity, fine particle size, and uniform quality.
Kaolin clay plays a vital role in ceramics, paper, paints, and various industrial applications due to its excellent plasticity, brightness, and low impurity levels. Through modern washing, refining, magnetic separation, and micronizing processes, we maintain controlled particle size distribution and minimal iron content, meeting precise buyer specifications for industrial formulations.
Product Highlights:
Typical Chemical Composition of Kaolin Clay:
| Component | Typical Percentage |
|---|---|
| SiO₂ (Silicon Dioxide) | 45 – 50 % |
| Al₂O₃ (Aluminium Oxide) | 35 – 40 % |
| Fe₂O₃ (Iron Oxide) | 0.3 – 1.5 % |
| TiO₂ (Titanium Oxide) | 0.5 – 2 % |
| CaO (Calcium Oxide) | 0.1 – 0.5 % |
| MgO (Magnesium Oxide) | 0.1 – 0.5 % |
| LOI (Loss on Ignition) | 12 – 14 % |
High-Grade Kaolin (Ceramic / Paper Industry):
Higher quality kaolin used in ceramics and paper coating applications usually contains improved brightness and lower iron content, which directly affects product whiteness and surface quality.
Typical Chemical Composition:
| Component | Typical Percentage |
|---|---|
| SiO₂ (Silicon Dioxide) | 46 – 49 % |
| Al₂O₃ (Aluminium Oxide) | 37 – 39 % |
| Fe₂O₃ (Iron Oxide) | < 0.5 % (very important for whiteness) |
| Brightness | 85 – 92 % |
Low iron content plays a critical role in achieving superior whiteness, which is especially important for ceramic bodies, paper coating, and high-quality paint formulations.
Theoretical Composition of Pure Kaolinite:
If the mineral is composed of 100% pure kaolinite, the approximate chemical composition is based on its natural crystalline structure.
Approximate Composition:
| Component | Typical Percentage |
|---|---|
| SiO₂ (Silicon Dioxide) | 46.5 % |
| Al₂O₃ (Aluminium Oxide) | 39.5 % |
| H₂O (structural water / LOI) | 14 % |
