Frequently Asked Questions
Q
What are the primary chemical components of the mica substrate?
The primary chemical components are Silicon Dioxide (SiO₂) ranging from 42% to 50% and Aluminum Oxide (Al₂O₃) ranging from 25% to 38%, which together form the core aluminosilicate structure.
Q
Why does the Iron Oxide (Fe₂O₃) concentration vary between 0.5% and 6%?
The concentration of Fe₂O₃ fluctuates based on the natural source of the mica mineral and the specific color systems intended for the final pigment formulation.
Q
Are the colorants and pigments customizable?
Yes, the colorant or pigment layer is fully customizable depending on the desired aesthetic finish, hue, and specific application requirements.
Q
What roles do Potassium Oxide (K₂O) and minor oxides play in the composition?
Potassium Oxide (K₂O) functions as the typical interlayer alkali component (7% - 11%), while minor components like MgO, CaO, and Na₂O provide structural integrity within natural mineral limits.
Q
What are the maximum thresholds for Calcium Oxide (CaO) and Sodium Oxide (Na₂O)?
Calcium Oxide (CaO) is strictly controlled to <=2%, and Sodium Oxide (Na₂O) is kept <=1.5% to maintain consistent chemical stability.
