What is silica? And its application

What is silica: Silica is one of the best and most important components of sand filtration. For this reason, it is sometimes called sand filtration silica. Silica has the chemical formula SIO2, which is extracted from the silica mine and is one of the minerals that is widely used in many cases, including the water industry. Included in working sand filtration system. Types of silica rocks produced by Hamedan Silica as the largest supplier of equipment and chemicals used in water and wastewater treatment in terms of quality and type of mineral material are:

Excellent degree
Classy
Grade 2
Amorphous silica

In the continuation of this article, we will introduce you to what is silica solvent, determining the percentage of silica purity, melting point of silicon dioxide, etc.

Micronized silica

Hamedan micronized silica or powdered silica is one of the most widely used minerals and is produced in various meshes including 180 mesh, 230 mesh, 325 mesh with a purity of over 99%. The word mesh is used in many scientific or commercial subjects, but few know its meaning. It is better to know that mesh has a special application in every industry and is of great importance and value in the production of micronized powder. Mesh in soil science refers to the granulation of the soil in order to sift it; That is, the size of the soil particles to pass through the sieve is called the mesh. In this article, we will review the applications and prices of micronized silica and purchase micronized powder.In the continuation of the Hamadan Silica online store, we will discuss this issue.

Application of premium silica

The best type of silica available in the market is an excellent sample of this element and is used in many industries, such as: glass industry, chemical, ferro-silica production, aquarium sand, artificial stone production, glazing industry, glass wool production To take.

First class silica

First-class silica is one step lower than premium, but there was no reason for its low quality and it is used in many industries, such as:

Production of cast sand
Sandblast sand

Production of sand filtration
Water and wastewater filtration

Grade 2 silica

This type of silica is two steps lower than Mumtazo and one step lower than grade 2 and is used in many industrial cases such as production of bricks, lime sand, light brick, cement factories, lightweight concrete, etc. It can be said that grade 2 silica is mostly used in civil engineering and urban planning. People who work in this type of job should be careful to be safe from the harms of this substance. For information on its harms, you can refer to the article What are the harms of silica.

What is amorphous silica?

Amorphous silica is a type of silica whose structure breaks very quickly at high temperatures and, unlike all other cases, silica is brittle and soft. This type of silica is widely used in the following industries:

Silica gel
Concrete Additives
Making optical fibers
Making silicone
Silicates

Types of silica rocks in nature

Silica is freely available in nature in three types of crystals, hidden crystals and hydrated hidden crystals. Which we will explain in the following

Quartz

Quartz shows good stability at normal pressures and temperatures. Starch silica is mostly found in nature in the form of quartz, the mineral of which has an extremely high hardness. In addition, this type is one of the silica polymorphs.

Silica sand

When quartz sandstones are crushed naturally, these grains of sand, limestone, iron oxide, and clay adhere to the rest of the material to form sandstone.

Flint

It is composed of water, calcium carbonate and very fine quartz crystals. The color of this material is dark and is available in the color range of light brown, black and gray. If burned, it will turn white. Flint also results from the dissolution of the siliceous skeleton of spongy animals in seawater and their deposition in the seabed.

In addition, this element after mining and processing in various forms can be used in various applications. For more information on examples and their applications, see What is Silica Crystal, What is Silica Soil, and What is Silica Powder?

Melting point of silica (melting point of silicon dioxide)

Silicon dioxide or silica is the most common substance and element in the Earth’s crust. This material is used in various industries due to its extraordinary properties. One of its excellent characteristics is the melting point of silica, which is 1170 ° C. Among these, the melting point of silicon carbide is 2730 ° C and the melting point of silicon tetrachloride is -74.68 ° C.

What is silica solvent?

In the production method of silica nanoparticles and its chemical nature can not be dissolved in aqueous solvents and many other conventional non-aqueous solvents. Due to this feature of stable suspension of silica nanoparticles, this material is considered in most industrial industries. Colloidal silica is an example of a type of silica. Acetone, alcohol and polar solvents have the ability to combine with colloidal silica. Of course, there is a limit to the amount of solvent used in silica cell to gel.

Determining the percentage of silica purity

Silica is a chemical compound that in pure form or in combination with silicate minerals makes up about 60% of the earth’s solid crust. The purity of silica is the presence of impurities inside the silica such as dust, glass and plastic. Inside silica packs. The purity of silica rock in Hamedan silica group is over 95% and only one wash after charging the silica is enough to ensure the high efficiency of sand filtration.

Physical properties of silica used in sand filtration tank

Effective sizes: 2.5 to 20 mm
Uniformity coefficient: 1.3 – 1.7
Specific weight: 2.67
Hair Hardness: Seven (7)
Density: 105 – 115 pounds per cubic foot
Silica density: 2.65 g / cm³

Types of silica sizing

The sizing of silica in sand filtration is as follows:

1.5 – 5 mm
3-5 mm
5- 8 mm
8 – 12 mm

What is oral silica drops?

These drops are used to stimulate fibroblasts and steve blasts. This substance produces collagen and is used in bones, cartilage, tendons and muscles apart from human skin. Collagen is present in about 80% of connective tissues; So it is a vital element in the body. With age, its amount decreases, which must be compensated through oral silica.

Purchase and price of high quality silica

Silicon dioxide with the chemical formula sio2 is one of the most common oxide compounds in the Earth’s crust. This element is used in various industries such as glassmaking, plastics, adhesives, jewelry, water purification, construction, etc. You definitely need it in any field. Now that you are familiar with its characteristics such as the melting point of silicon, the determination of the percentage of purity of silica and the solvent of silica, you are familiar with it; To buy high quality silica, you can refer to Hamedan Silica website as the best silica sales collection.
