Dehydration kinetics of muscovite by in situ infrared

Dehydration behavior of muscovite flake was investigated at 760–860°C by using in situ high-temperature IR microspectroscopy for the OH absorption band around 3,620 cm−1. Isothermal kinetic heating experiments at each temperature gave detailed decrease curves of the OH band area with time. These curves have been simulated by …

Muscovite: Complete Guide (2024) | Healing Crystals Co.

Put simply, muscovite's definition describes an abundant silicate mineral and hydrated phyllosilicate mineral rich in both aluminium and potassium. The muscovite mineral is part of the mica group. It has perfect cleavage (a typically white to silver color), a vitreous, silky luster, and a monoclinic crystal system.

Muscovite

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 …

Muscovite: Properties, Uses, Occurrence | Geology In

Muscovite, also known as "silver mica" or "potassium mica," is a common rock-forming mineral belonging to the mica group. It's composed primarily of potassium, aluminum, and silicate, and boasts a distinct layered structure that allows it to easily split into thin, flexible sheets. Muscovite possesses a unique combination of properties that ...
