The nature of quartz mainly includes the following aspects:

Hardness: Quartz has a hardness of 7, which is a high-hardness mineral. This means that it has good wear and corrosion resistance.

Optical properties: Quartz has a high degree of transparency and can be used in the manufacture of optical instruments and glasses. In addition, specific changes in its internal structure allow quartz to be used to make piezoelectric crystals, among other things.

Chemical stability: Quartz is insoluble in any acid other than hydrofluoric acid and has high chemical stability.

Coefficient of thermal expansion: The coefficient of thermal expansion of quartz is small, making it difficult to deform at high temperatures.

Electrical properties: Quartz has certain piezoelectric and thermoelectric effects, which means that when subjected to pressure or temperature changes, it will generate electricity.

Quartz has a wide range of uses, mainly based on its properties:

Glass manufacturing: Quartz is the main raw material for the manufacture of glass, and the glass made is called quartz glass, which has high heat resistance and chemical stability.

Ceramics and refractories: Quartz is used in the production of ceramics and refractories, which can improve their heat resistance and hardness.

Semiconductor industry: Pure quartz is a good semiconductor material, often used in the manufacture of electronic devices.

Abrasives and abrasives manufacturing: Quartz sand is a commonly used abrasive material that can be used to grind a variety of hard materials.

Industrial fillers: Quartz can be used as a filler in industries such as rubber, plastics and coatings to improve the performance of products.

Gem and mineral collections: Pure quartz (crystal) and some varieties of silica crystals have good optical properties and are often made into gems or used in collections.

Construction: Quartz can be used in the manufacture of building materials such as concrete and cementing materials.

Foundry and metallurgical industry: Quartz is a raw material for the foundry and metallurgical industry, which can improve the heat resistance and oxidation resistance of metals.

Aerospace field: Quartz fiber has good insulation and high temperature resistance, and can be used to manufacture thermal insulation materials in aerospace spacecraft.

Chemical reactants: Quartz is often used as a silicon source in chemical reactions, such as the synthesis of silanes, silicates, etc.

Other: Quartz can also be used to make coatings, dyes, pesticides, etc.

In general, the wide application of quartz is closely related to its unique physical and chemical properties. With the development of science and technology, new uses of quartz will continue to be discovered.
