Product Detail
Mica is a naturally occurring mineral that is based on a collection of silicate minerals and composed of varying amounts of potassium, iron, aluminium, magnesium and water, all having nearly perfect basal cleavage. Mica occurs in igneous, metamorphic and sedimentary regimes and is widely distributed globally. Large crystals of mica used for various applications are typically mined from granitic pegmatites.
Chemical Composition:
The general formula for mica group minerals is XY₂₋₃Z₄O₁₀(OH, F)₂:
- X: Can be K, Na, Ba, Ca, Cs, (H₃O), or (NH₄).
- Y: Includes Al, Mg, Fe²⁺, Li, Cr, Mn, V, and Zn.
- Z: Comprises Si, Al, Fe³⁺, Be, and Ti.
The chemical properties of mica minerals vary depending on the specific type of mica. However, all micas are silica (SiO2), aluminum oxide (Al2O3), and potassium oxide (K2O). Some micas may contain other elements, such as iron oxide (Fe2O3) and magnesium oxide (MgO). The following table shows the chemical composition of some common mica minerals:Of the 28 known species of mica, six are common rock-forming minerals:
| Mica mineral | SiO2 | Al2O3 | K2O | Fe2O3 | MgO |
| Muscovite | 45.57 | 33.1 | 9.87 | 0 | 0 |
| Biotite | 47.7 | 30.9 | 3 | 10 | 3 |
| Phlogopite | 47.5 | 31 | 3 | 0 | 15 |
- Muscovite: The common light-colored mica.
- Biotite: Typically black or nearly black.
- Phlogopite: Typically brown.
- Paragonite: Macroscopically indistinguishable from muscovite.
- Lepidolite: Generally pinkish to lilac; occurs in lithium-bearing pegmatites.
- Glauconite: A green species found sporadically in marine sedimentary sequences.
Physical Properties of Mica:
| Property | Muscovite | Biotite | Phlogopite |
| Hardness (Mohs scale) | 2.5-3 | 2.5-3 | 2.5-3 |
| Specific gravity | 2.76-2.85 | 2.9-3.3 | 2.8-3.1 |
| Cleavage | Perfect basal cleavage | Perfect basal cleavage | Perfect basal cleavage |
| Luster | Pearly or vitreous | Pearly or vitreous | Pearly or vitreous |
| Color | Colorless to white | Black | Brown |
- Perfect Cleavage: Mica splits into thin, elastic sheets due to its perfect cleavage.
- Luster: Micas exhibit a splendent luster, with some cleavage faces appearing pearly.
- Heat Resistance: Mica is heat-resistant.
- Electrical Insulator: It does not conduct electricity.
- Elasticity and Flexibility: Mica sheets and flakes are flexible.
- Translucency: Mica is translucent and optically flat.
- Colorless in Thin Sheets: When beaten into thin sheets, mica appears colorless.
- Stability: Micas remain stable when exposed to electricity, light, moisture, and extreme temperatures.
