Biotite is a common phyllosilicate mineral within the mica group, with the approximate chemical formula K(Mg,Fe) 3 AlSi 3 O 10 (F,OH) 2.More generally, it refers to the dark mica series, primarily a solid-solution series between the iron-endmember annite, and the magnesium-endmember phlogopite; more aluminous end-members include siderophyllite.Biotite was named by J.F.L. Hausmann in 1847 …
Additional Information. Mica is an excellent protection mineral, as it is not only insulating, but its reflective surface also deflects negative energy and psychic attack. Because of its non-conductivity, it is also very helpful in creating a shield from electromagnetic radiation, and can be placed on a desk between the user and a computer.
mica (mī´kə), general term for a large group of minerals, hydrous silicates of aluminum and potassium, often containing magnesium, ferrous iron, ferric iron, sodium, and lithium and more rarely containing barium, chromium, and fluorine.
Mica Properties and Meaning. Mica is a member of the Silicates family. It is a very shiny crystal and is a common companion for other minerals like Tourmaline, Aquamarine, Fuchite and Aventurine. Read more about Mica crystal healing properties below, with photos and desktop image!

Biotite, another common mica, is recognized by the IMA as a mineral group of related micas rather then as an individual mineral type. Phlogopite is one of the member minerals of the Biotite group, and is chemically and structurally similar to the other Biotite minerals.
It is almost insensitive to atmospheric weathering and offers greater resistance to outside chemical influence. Muscovite Mica is harder than Phlogopite Mica. Muscovite Mica is the most commonly used Mica in electrical insulation and since it has the best electrical properties of all Mica.
Mica is the name given to a group of silicate minerals that have silicon and oxygen as their two major components. The Mica family of minerals includes several variations based on chemical composition and characteristics.
The mica minerals are distinguished by their perfect basal cleavage, which means that they are easily split into thin, often transparent, sheets. Two micas, biotite, and muscovite, are so common that they are considered rock-forming minerals. The rest are relatively uncommon, but phlogopite is the most likely of these to be seen in the field.
Mica is a naturally occurring stone that directly applies to a set of minerals containing silica in its highest form. This mineral is mostly used in gypsum wallboard combined compound where it acts as wadding and prevents cracking. There are a variety of uses of this mineral such as:
