The material is primarily composed of silicon dioxide (SiO2 at 38%–45%) and magnesium oxide (MgO at 24%–29%), which together form the robust silicate structural framework.
Fluorine (7%–10%) replaces the hydroxyl (OH) groups found in natural mica, significantly improving thermal resistance, electrical insulation, and chemical stability under extreme conditions.
Iron oxide (Fe2O3) is a controlled impurity. Maintaining levels ≤ 0.5% ensures superior optical clarity, high whiteness, and optimal dielectric performance.
Yes. Titanium dioxide (TiO2) content exists in trace amounts by default but can be customized according to the specific technical grade and client requirements.
Alumina (Al2O3 at 10%–15%) enhances structural integrity, mechanical strength, and chemical durability across various industrial applications.
Potassium oxide (K2O at 8%–12%) functions as an interlayer cation, maintaining the defined crystalline structure and uniform layer cleavage.
