Applications of silica - Silis Momtaz Davarkia

Silica is one of the most abundant minerals in nature, which is used in many industries. Due to its unique characteristics, this substance plays a vital role in the production and processing of various products. In this landing, we will examine the uses of silica and its benefits.

What is silica?

Silica (SiO₂) is a chemical compound found naturally in rocks and soils. Due to its crystalline and non-crystalline structure, this material has wide applications in various industries. Silica is one of the most abundant minerals in nature and is used as one of the main components in the production of many industrial products.

use of silica

Silica is used as a key raw material in various industries. Some of the most important applications of silica are:

Glass industry:

premium silica is used as one of the main raw materials in glass production. This material increases the transparency and strength of manufactured glass and is used in the production of all kinds of construction glass, containers and glass accessories.

Construction industry:

In making mortar and concrete, silica is used as an additive. This material increases the strength and durability of structures and is especially used in the production of advanced and resistant concrete.

Ceramics and porcelain:

Silica is used as a main material in the production of ceramics and porcelain. This material helps to improve the quality, strength and appearance of the products and is used in the ceramic industry and the production of quality China.

Chemical industry:

Silica is used in the production of various chemicals and as a filter in water and wastewater treatment. This substance can be used as an additive in the production of paints, coatings and other chemical products.

Gas and oil industry:

Silica is used as an abrasive material in oil and gas drilling and helps to increase the efficiency of this process.

Electronics industry:

Silica is used in the production of semiconductors and other electronic equipment, and due to its electrical properties, it plays a role in the manufacture of chips and electronic devices.

Silica types

Silica is generally divided into two main categories:

Crystalline silica: This type of silica has a regular and specific structure and is usually found in sedimentary and volcanic rocks. Among its types, we can mention quartz.
Amorphous silica: This type of silica has an irregular structure and is usually used in the production of glass and ceramics.

Silica is divided into different categories based on mineral and degree of purity:

Types of silica based on mineral:

Quartz: It is one of the most common forms of silica that is found abundantly in nature and is used as a base stone for the production of glass and ceramics.

Cristobalite: Another type of silica that forms at high temperatures and is used in the production of quality ceramics.

Trimite: a type of silica that is used in certain industrial processes and has unique properties due to its special structure.

Types of silica based on the degree of purity:

Industrial Silica: Silica that has medium purity and is used in various industries such as making mortar, concrete and glass.

Pure Silica: High purity silica that is used for special and sensitive applications such as electronics industries and laboratories.

properties of silica

Silica has unique physical and chemical properties that make it suitable for use in various industries:

High resistance: Silica has high mechanical and thermal resistance.
High melting point: This feature makes silica usable at high temperatures.
Compatibility with the environment: It exists naturally in the earth and its use does not harm the environment.
Economy: Silica production and processing costs are lower than many other raw materials.

Silica, as a key material in various industries, has many uses and properties, each of which somehow helps to improve the quality of products and services. Due to the characteristics and benefits of silica, this material is still growing and developing in various industries.
