Mica (muscovite)
HS code 252520Formula KAl₂(AlSi₃O₁₀)(OH)₂
Mica flakes bridge and seal fractures and porous zones where drilling fluid is lost. Muscovite is platy, flexible, chemically inert and stable above 800 °C, and works in both water-based and oil-based muds.
- Lost circulation control
- Bridging and sealing
- Wellbore stability
- Chemically inert
