  • Muscovite Wikipedia

    Muscovite (also known as common mica, isinglass, or potash mica) is a hydrated phyllosilicate mineral of aluminium and potassium with formula K Al 2 (AlSi 3 O 10)(F,OH) 2, or 2 (Al 2 O 3) 3 (SiO 2) 6 (H 2 O).It has a highly perfect basal cleavage yielding remarkably thin laminae (sheets) which are often highly elastic.Sheets of muscovite 5 meters × 3 meters (16.5 feet × 10 feet)

    Pashley (1981b) reported two types of behavior for the interaction of muscovite mica surfaces in alkali metal chlorides: 1. Below a critical concentration (e. g., about 1 × 10 − 2 M NaCl and 5 × 10 − 4 M CsCl), which was different for each cation, the DLVO theory was followed from large distances of separation (1000 Å), with surface potentials in the range of —70 to —130 mV,
