How to Distinguish between Quartzite and Quartz?

Many people think that quartzite and quartz are the same thing, because just from the name alone, it does not seem to be much different, but in fact, quartzite and quartz are in terms of composition, production environment, appearance, performance, and application. All are different. Today, let’s take a look at what quartzite and quartz are and what are the differences between them.

I. What is Quartzite and Quartz: The Most Comprehensive Introduction

1. Quartzite


The main mineral of quartzite is quartz, which may contain mica minerals, hematite, goethite, etc. Quartzite is a metamorphic rock mainly composed of quartz with a quartz content of more than 85%. It is formed by metamorphism of quartz sandstone and siliceous rock.

Quartzite is generally formed by recrystallization of quartz sandstone or other siliceous rocks through regional metamorphism. It is also possible that siliceous rocks near the magma undergo thermal contact metamorphism to form quartzite.


Appearance features

Quartzite is generally light-colored or white, dense and hard, but its particles are often formed into dense blocks, which are not easy to distinguish with the naked eye.

Scope of application

At present, quartzite plates are mainly used in cabinet countertops, sinks, bar counters, coffee tables, floors and interior walls. It can completely replace natural stone, high-grade ceramics, wood and metal decorative materials. At the same time, the application of quartzite is constantly changing, the application share of cabinet countertops is large, and the application ratio of ground is also increasing significantly.


Performance advantages

1. Quartzite has high hardness and low water absorption, and can be used as a building material, especially for outdoor stones, such as paving stones, floors, cladding and so on.

2. Quartzite has fine particles and compact structure, and can be used as a stone for handicraft carving, especially solid-colored quartzite.

3. Due to the unique crystal structure of quartzite, it presents colorful and unique colors and textures, with special decorative effects.

4. Quartzite is widely distributed, easy to mine, easy to process, and low cost. It is a stone product with high cost performance.

5. Quartzite is widely used and can be used as an important raw material for manufacturing glass, ceramics, metallurgy, chemical industry, machinery, electronics, rubber, plastics, coatings and other industries.

6. Quartzite has excellent high temperature resistance and can be used as a refractory material for steelmaking through physical processing into different particle sizes.

2. Quartz


Quartz, a professional term in geology, generally refers to low-temperature quartz, which is the most widely distributed mineral in the quartz group. The main component is SiO2, which is colorless and transparent, often contains a small amount of impurities, and becomes a translucent or opaque crystal with a hard texture.

Quartz is a mineral resource with very stable physical and chemical properties, and the crystal belongs to the oxide mineral of the trigonal system. Quartz stone, also known as silica, is mainly the raw material for the production of quartz sand (also known as silica sand), as well as the raw material for quartz stone refractories and sintering ferrosilicon.

Appearance features

Quartz is a hexagonal column and a rhombohedral polycrystalline crystal, the column surface has horizontal lines, the chemical composition is silicon dioxide, generally dense block, vitreous luster.

Scope of application

1. Quartz stone countertops

The most widely used quartz stone plates are cabinet countertops, handwashing countertops, counter tops (banks, mobile telecommunications business halls, cashier counters, etc.), bar counters (bars, western restaurants, etc.), dining tables (such as McDonald’s and KFC’s desktops).

2. Quartz stone wall

Shower wall panel, kitchen wall panel, background wall, etc.

3. Quartz stone floor

It can be used for floor decoration in home decoration, commercial decoration and engineering decoration.


Performance advantages

1. The hardness of quartz stone is very high. In nature, the hardness of quartzstone is second only to the hardness of diamond, so when used in daily life, some architectural parts made of quartz stone material will be very hard, and not easy to damage. This well reflects the high durability of this type of decoration in a whole set of decoration.

2. The advantage of quartz stone is that its high temperature resistance is very good, because the melting point of quartz stone is above 1300 degrees, and it can be completely flame retardant, so quartzstone is very suitable for being placed in the kitchen material. Because of its flame retardancy, if an accidental fire occurs while cooking in the kitchen, it cannot spread to other rooms of your own.

3. Quartz stone is very convenient to clean, because the surface of quartz stone is generally polished and smooth. After some stains are splashed on it, some conventional detergents and water can be used to remove the stains well, which can save a lot of time in the kitchen. So these are some of the advantages of using quartzstone material.

4. Some materials made of cabinets will be easily scratched, but quartz stone countertops will not be like this. The compression of vacuum makes the hardness of quartzas high as 5. Everyone knows that the highest hardness is 10, so quartz stone will not be easily scratched. Although it is not a natural stone, after a special process, the quartzstone also has the feeling of a real stone.


II. What is the difference between quartzite and quartzite?

1. Different ingredients

The content of quartz is different. Quartzite is a metamorphic rock with a quartz content of more than 85%. It is generally formed by sandstone or other siliceous rocks through regional metamorphism and recrystallization. Quartz is a mineral resource with very stable physical and chemical properties. Quartz is an abbreviation for the wrench produced by the current quartz stone plate manufacturers. Because the main component of the wrench has a quartz content of more than 93%, Therefore, it is called quartz stone.

From the perspective of the light float, quartz has a glass light method, and the color is white with a little gray. Quartzite generally has a massive structure, a granular metamorphic structure, and also contains a small amount of feldspar, sericite, amphibole, pyroxene, etc. It has various colors and high hardness, and can be used as building materials or railway track-laying stones. The fine solid-color particles can be used as raw materials for handicraft pith engraving. Quartzite is a natural stone, while quartz is an artificial stone.

2. Different production environment

Quartzite is fired in a 15,000-ton press at temperatures above 1,200 degrees Celsius. Quartz stone is made by vacuum pressing with a press and then heating and curing.

3. Different appearance

Quartzite is mainly large-sized, usually 3-20 mm thick. The texture is close to natural stone; the green body and the surface color are consistent to form a whole. Quartz stone is rich in appearance and color, but its texture is very different from natural stone, and its thickness is usually 8-30 mm.

4. Different performance

Quartzite has excellent comprehensive performance, waterproof, fireproof, high temperature resistance (1200), low temperature resistance, high concentration acid and alkali resistance, pollution resistance, wear resistance, impact resistance, no contact with food, no radiation, environmental protection, recycling, durability, and no fading.

The performance of quartz stone is worse than that of quartzite. For example, open fire is flammable and releases paint smell. High temperature will cause discoloration, yellowing and aging. It can withstand low concentration of acid and alkali, high temperature of 300, and is not resistant to oil stains. It performs well in terms of water resistance and scratch resistance.

5. Different applications

Quartzite has strong performance and plasticity, and can be deeply processed. It can be used as both a decorative material and a main structural material. It is widely used in countertops, desktops, walls, floors, facades and other fields. The main application areas of quartz stone are countertops and table tops.

Many people think that quartzite and quartzite are the same thing, because just from the name alone, it does not seem to be much different, but in fact, quartzite and quartzite are in terms of composition, production environment, appearance, performance, and application. All are different. Today, let’s take a look at what quartzite and quartzite are and what are the differences between them.
