Frequently Asked Questions
What are the primary chemical components of the mica substrate?
The main components are Silicon Dioxide (SiO2) ranging from 42% to 50% and Aluminum Oxide (Al2O3) ranging from 25% to 38%, which together form the structural silicate and alumina matrix of the mica.
Why does the Iron Oxide (Fe2O3) content fluctuate between 0.5% and 6%?
The concentration of Fe2O3 varies primarily depending on the geographic origin of the raw mica ore and the specific color system or opacity requirements of the intended application.
What function does Potassium Oxide (K2O) serve in this material?
Potassium Oxide (7% - 11%) acts as the typical alkali interlayer constituent in mica minerals, playing a key role in stabilizing the crystal lattice structure and layer cleavability.
Can the colorant or pigment formulation be tailored for specific industrial applications?
Yes, the colorant or pigment portion is fully customized. The composition is tailored according to precise hue requirements, coating processes, and performance demands of the end product.
What are the minor chemical components present in the mixture?
Minor mineral and alkali components include Magnesium Oxide (MgO at 0.2% - 3%), Calcium Oxide (CaO <= 2%), and Sodium Oxide (Na2O <= 1.5%), which are naturally occurring trace elements.
