Hardness: Quartzite is very hard and ranks around 7 on the Mohs scale, which makes it harder than even granite.
Quartzite is a hard, metamorphic rock that was originally sandstone. Through a process of high heating and pressure, the sandstone is transformed into quartzite. This metamorphism causes the quartz grains in the sandstone to recrystallize and fuse together, making quartzite a very strong and durable rock.Quartzite is prized for its strength, durability, and aesthetic appeal, making it a popular choice for both functional and decorative applications in various industries. Here are some key characteristics and uses of quartzite:
Hardness: Quartzite is very hard and ranks around 7 on the Mohs scale, which makes it harder than even granite.
Appearance:: It typically has a glassy or crystalline appearance. It can be found in a variety of colors including white, gray, pink, red, yellow, blue, green, and orange, depending on the mineral impurities present.
Durability: It is highly resistant to chemical weathering and physical wear, making it a durable material.
Non-porous:Unlike sandstone, quartzite is non-porous, which means it does not absorb water and is resistant to staining
Construction:Due to its hardness and resistance to weathering, quartzite is often used in construction, particularly for countertops, flooring, and stair steps. It is also used as a decorative stone in architecture.
Road Material: It is sometimes used as an aggregate in road construction and as a railway ballast due to its durability.
Industrial Uses: Quartzite can be used as a raw material in the production of silica for the glass industry and for silica sand in foundry applications.
