| Chemical Component | Typical Content | Description |
|---|---|---|
| SiO2 | 38% - 45% | Main silicate component |
| Al2O3 | 10% - 15% | Alumina component |
| MgO | 24% - 29% | Magnesium component |
| K2O | 8% - 12% | Potassium component |
| F | 7% - 10% | Characteristic component of synthetic fluorophlogopite |
| Fe2O3 | ≤ 0.5% | Controlled low impurity |
| TiO2 | Trace or customized | Depends on product grade |
The primary matrix is composed of Silicon Dioxide (SiO2) at 38% - 45% and Magnesium Oxide (MgO) at 24% - 29%, forming a stable silicate network.
Fluorine (7% - 10%) is the defining characteristic of synthetic fluorophlogopite, replacing hydroxyl ions to provide superior thermal stability and electrical insulation compared to natural mica.
Iron Oxide (Fe2O3) is strictly limited to ≤ 0.5% as a controlled impurity, ensuring optimal whiteness, transparency, and electrical non-conductivity.
Yes, Titanium Dioxide is present in trace quantities but can be customized according to specific product grades and application requirements.
Alumina (10% - 15%) enhances structural strength and heat resistance, while Potassium Oxide (8% - 12%) acts as an interlayer cation to stabilize the crystal lattice.
