While it’s commonly known as a mineral that makes up the composition of a variety of rocks, muscovite is a standalone material. It comes with its own properties and uses that are worth noting.
As previously mentioned, muscovite is the mica family’s most prevalent mineral with relatively thin grains. It is also one of the essential rock-forming substances that may be found in metamorphic, igneous, and of course, sedimentary rocks like kaolin clay.
In kaolin forming, muscovites mineral is known for being a non-expanding mineral because it’s the substance that makes kaolin won’t expand when it comes into touch with water. However, when muscovite is extracted and is used as a standalone mineral, it can split into very thin sheets.
The ability makes muscovite to be the early material of window panes. In the 17th century, it was deliberately mined for this particular purpose from igneous rock in Moscow. The nickname “Muscovy glass” was later given to these panes. It is also assumed that the name of this mica mineral was derived from them.
Sedimentary, metamorphic, and igneous rocks are where muscovite is generally founded. It is a primary mineral found in igneous rocks, particularly granitic ones. In granite, muscovite often occurs in the form of large-sized crystals that have a pseudo-hexagonal structure. Those crystals are dubbed as “books” because of their ability to split into thin sheets like an actual book.
In terms of physical properties, it’s safe to say that muscovite is a mineral that can easily be identified. It’s all because of the perfect cleavage of this mica, which enables it to be split into fine, elastic, translucent sheets. It is the only mineral on the plant with these characteristics.
When chromium is used to replace aluminum, muscovite will naturally turn green, earning it the name “fuchsite.” This mineral is typically found dispersed in metamorphic rocks. It’s often plentiful enough to give the material a somewhat noticeable green tint known as verdite rocks.
Some auto industries, particularly those in the United States, use muscovite in order to elevate the quality of plastic auto parts. When it’s used in plastics, the particles of this fine-grained mica will absorb vibration and sound. The stability, strength, and stiffness of mechanical properties can also be improved with the use of muscovite.
While it’s mostly known for being an essential mineral that composes various types of rocks, one of them being kaolin clay, muscovite comes with its own properties that cannot be overlooked. The properties of this mica mineral even lead many to make the most of it for various industrial purposes.
The use of muscovites mineral is even now growing along with the advance of technology. It’s all because of its characteristics as an elastic mineral that makes it highly versatile to be incorporated in various applications.
