Main Constituents of Granite

Granite is a type of igneous rock that is primarily composed of two main constituents, silica and aluminium. Let us understand these constituents in detail.

Silica

Silica, also known as silicon dioxide (SiO2), is a compound that is abundantly found in the earth's crust. It is the second most abundant element after oxygen and makes up about 59% of the earth's crust. Silica is found in different forms such as quartz, flint, and chert. In granite, silica is present in the form of quartz.

Aluminium

Aluminium is a chemical element with the symbol Al and atomic number 13. It is a silvery-white, soft, non-magnetic, ductile metal. Aluminium is the third most abundant element in the earth's crust, after oxygen and silicon. In granite, aluminium is present in the form of feldspar.

Other Constituents

Apart from silica and aluminium, granite also contains other minerals such as mica, hornblende, and biotite. These minerals give granite its characteristic texture and color.

Uses of Granite

Granite is a popular building material and is used for making countertops, flooring, and monuments. It is also used in landscaping and as a decorative stone. Granite is known for its durability and strength, which makes it a preferred choice for construction.

Conclusion

Silica and aluminium are the two main constituents of granite. Silica is present in the form of quartz, while aluminium is present in the form of feldspar. Granite is a popular building material due to its durability and strength.
