a silicate mineral characterized by sheet cleavage; i.e., it separates in thin sheets. Biotite is ferromagnesian black mica, and muscovite is potassic white mica. Sometimes mica is used as a lost circulation material in drilling.
Any of a group of silicate minerals which crystallize to form a material which can be separated in very thin more or less elastic flakes. The principal micas are biotite or black mica and muscovite, a more or less colorless, translucent variety.
muscovite from mineral lab, monoclinic minerals, sheet silicates
Common mineral. Any of several shiny silica minerals that occur in igneous and metamorphic rocks. They split easily and are used as electrical insulators and in heating elements because of their resistance to electricity and heat.
a silicate mineral that forms thin transparent sheets.
A group of silicate minerals exhibiting perfect cleavage in one direction. Micas split into thin, tough, somewhat elastic plates with a splendent pearly luster. They are prominent rock-forming constituents of igneous and metamorphic rocks, and commonly occur as flakes, scales or shreds.
any of the group of minerals that are found in crystallized, thin elastic sheets that can be separated easily. They vary in color from pale green, brown, or black to colorless. Ground and used as a lubricant and coloring in cosmetics. Non-toxic and inert.
silicate mineral used in manufacturing of heat sensitive equipment.
A silicate which separates into layers and has high insulation resistance, dielectric strength, and heat resistance. It is used as an insulation wrap in wires and cables to a limited degree while radiation resistance requirements are severe and for high temperature work demanding good heat resistance.
The use of the mineral mica bonded with shellac to create translucent sheets .
Black, white, pinkish, purplish or yellowish mineral that splits into thin flakes and is composed mainly of potassium, sodium, magnesium or iron combined with aluminium, silicon and oxygen. It is chiefly used in industry.
Shiny silicate material, used to add sparkle
Micas are a group of silicate minerals that have a platy or sheet-like structure. This makes thin flakes of mica very easy to peel off. Muscovite and biotite are two of the commonest micas.
A mineral consisting of shiny, transparent, platelike chemical crystals.
A potassium aluminium silicate mineral which occurs in clay, china stone and granite (q.v.). It has a thin sheet-like form which promotes plasticity.

a mineral name given to a group of minerals that are similar in their physical
a naturally occuring mineral that has been used in electrical and thermal insulation for many years and is now beginning to be utilised for its optical properties
a silicate mineral that forms sheets or layers and contains aluminum, hydroxyl, and alkali ions: K2Al4Si6Al2O20(OH,F)4, K2(Mg,Fe)6Si6Al2O20(OH,F)4
A group of common rock-forming minerals that have a flat shape and cleave easily into thin layers or sheets. One common mica is biotite.
Any of a group of mineral silicates in a muti-layered form.
An earth mineral used as a pigment in cosmetics. Has light-diffusing properties.
Thin layers of mineral which when fused together, create a translucent shade material which emits a warm glow. Mica is used in its natural color or is often dyed amber.
A family of minerals with a common sheet-like internal structure. See also biotite and muscovite.
A silicate mineral used mainly as an electrical and heat insulator.
A silicate material used primariily as an electric and heat insulator.
A natural pearlescent mineral pigment.
Group of silicate minerals composed of varying amounts of aluminum, potassium, magnesium, iron and water. All micas form flat, plate-like crystals. Crystals cleave into smooth flakes. Biotite is dark, black or brown mica; muscovite is light-colored or clear mica. more details...
Midwest Insulation Contractors Association.
a mineral group composed of phyllosilicates (varying amounts of potassium, sodium, calcium, iron, magnesium, aluminum in Si4O10 base) with sheet-like structure and characterized by almost perfect basal cleavage.
A group of silicate minerals that cleave perfectly into thin sheets (see Biotite, Muscovite).
a group of minerals characterized by low hardness and breakage in one direction along thin layers, like pages in a book.
A family of silicate minerals which form very thin crystals which may be flexible and have the appearance of 'cellophane'.
A transparent mineral used as window material in high-temperature ovens.
A naturally occurring mineral, based on silica, which after treatment, is used as an effect pigment in coatings. Their special property is that light falling on a mica particle, depending on the angle of illumination, reflects the light with a change in colour. Because of this they are sometimes referred to as pearls. Alternate Term(s): Pearl
Mica is a soft, lightweight, transparent mineral that cleaves into thin, elastic sheets (it has a single perfect cleavage direction). It is used for lampshades and electrical insulators. There are about 30 different types of micas, ranging in color from yellow to green to gray to violet to white to brown. Mica has a hardness of 2.5 and a specific density of about 3. Tiny mica particles give the shimmer to aventurine (goldstone).
Is a mineral used as an electrical insulator in some neon electrodes. It is usually a semi clear very thin rectangular sheet.
a transparent, flaky material which spits into thin sheets and has excellent insulating and heat resisting properties, consisting of orthosilicates of aluminum or potassium, occurs naturally.
A group of soft silicate minerals that have perfect basal cleavage in one direction and can easily be split into characteristic thin, elastic, pearly sheets.
A mineral silicate that readily separates into thin sheets. When powdered, it is sometimes used as an inert pigment in paint products.
natural mineral for adding shine.
Silicate mineral that exhibits a platy crystal structure and perfect cleavage. Common forms of mica are biotite and muscovite.
A name of a group of transparent, flaky, colorful minerals approved for use in cosmetics, including the eye area.
A group of silicate minerals ranging from colorless to black characterized primarily by their ability to separate into very thin sheets. Finely pulverized mica is used as an inert pigment in paint. A sheet-like mineral found in small flakes in some natural clays; the material that shimmers in many low-fire pots of primitive cultures.
A group of minerals consisting of hydrous silicates of aluminum or potassium which are common in igneous and metamorphic rocks. Mica vary in color from pale brown or yellow to green or black and characteristically split into very thin leaves. Sheets of mica used in insulation and electrical equipment because of their resistance to electricity. The transparent forms are used in lanterns, the doors of stoves, etc.

The mica group of sheet silicate minerals includes several closely related materials having highly perfect basal cleavage. All are monoclinic with a tendency towards pseudo-hexagonal crystals and are similar in chemical composition. The highly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.
