What is Silica powder?

Silica powder is a mineral that consists of silicon dioxide (SiO2). Silica powder is in the form of white grains and is used as a popular material in glass making, tile making, ceramic, paint making, rubber, plastic, structural materials, waterproofing materials, coating and electronic industries.

Silicon powder or micronized silica powder is a byproduct of ferrosilicon alloy melting or industrial silicon, which is oxidized and cooled by the silicon vapor coming out of the chimney. Silicon powder is one of the best performing of all additives and also the most expensive. It is generally used only in concrete with high strength and durability.

Silica stone is one of the most widely used stones in nature, this stone is composed of a combination of silicon and oxygen, which must be powdered to use this product. Crystalline silica, also known as quartz, is a common mineral. It is found in soil, sand, granite, concrete, stone and many other materials.

Cutting, crushing, grinding, and drilling these materials creates a lot of dust that contains tiny particles of crystalline silica.

What is micronized silica powder?

Micronized silica powder is a white powder with very fine particles of silica (silica dioxide) that occurs naturally in igneous rocks or sand.

Due to its important properties such as heat resistance, corrosion resistance, wear resistance and high hardness, micronized silica powder is used as a widely used material in the production of industrial products as well as in the food and pharmaceutical industries. Also, it is used as an absorbent material in buildings to prevent moisture and improve air quality.

Properties of powdered silica and silica rock

Silica is a chemical element with the symbol Si and atomic number 14 in the periodic table and is found in nature as one of the most floating and scattered elements and in most sedimentary and igneous rocks as well as in soil, volcanic rocks and river sediments.

Due to its physical and chemical properties, silica is used as a widely used material in various industries. Among the important properties of powdered silica and silica stone, the following can be mentioned:

  • Physical properties: Silica has high hardness and compressive strength and also has good electrical and thermal properties.
  • Chemical properties: Silica has very high anti-corrosion properties and chemical resistance, and it also has the ability to stain and remove color.
  • Medical properties: Silica is also used in the pharmaceutical and medical industries due to its antiseptic, anti-inflammatory and high absorbency properties.
  • Industrial properties: Silica is used in various industries such as production of glass, paper, plastic, rubber and construction materials.

Chemical analysis of micronized silica

The chemical analysis of micronized silica can be different depending on the type of silica and the purpose of application. But in general, the chemical composition of micronized silica is as follows:

Silica dioxide (SiO2): The most common chemical compound is micronized silica, whose percentage is usually above 99%.

Mineral elements: micronized silica may contain other mineral elements such as aluminum, alkali metals, metals with high oxidation power, etc.

Saturating elements: These elements include iron, calcium, magnesium, potassium and sodium and may be present in micronized silica.

Also, the amount of heavy metals in micronized silica should also be measured. In general, for the chemical analysis of micronized silica, various techniques such as UV-Vis spectroscopy, FTIR, XRD and grain analysis are used.

Types of silica powder

This type of hard stone is one of the most common materials on earth that exist in various types. Silica is used in industrial, food and beverage fields. Quartz raw materials are used for the production of opaque, artificial and clear glass, as well as for the production of ceramics. Silica exists in nature in the following three forms.

  • Quartz: This type is one of the polymorphs of silica and is stable at normal temperature and pressure due to its high hardness. The most type of silica in nature is this type of mineral.
  • Sandstone: Silica sand is a type of sedimentary quartz that is crushed naturally. These grains are stuck together by particles of clay, lime, iron oxide or other materials.
  • Flint: This type is composed of quartz, calcium carbonate, water and organic matter and its color is light brown, black or gray. This type of siliceous skeleton of sponge animals dissolves in sea water and settles on the seabed.

Application of pure silica powder

Since silica rock has many applications, the type of silica powder, which is an example of its processing product, is also used in various industries. Examples of its uses include foundry, ceramic, plastic, water turbidity treatment, sand filtration, etc.

Perhaps the most interesting application of buying pure silica powder is in the field of making sports equipment. In this context, colored micronized silica powder is used to increase attractiveness and beauty.

Because the resistance of this material is high; They use it to make devices and buildings that need resistance. One of its important uses is in the construction industry. Buying micronized silica powder for concrete is an example of its important applications that increases the strength of your structure.

Of course, it should be noted that the higher the purity of silica, the more durable your final product will be.

Some factories also produce synthetic silica, but it all comes from silica sand. It is common to buy natural or synthetic silica powder (sugar granulated silica) in non-food products.

  • Glass industry: micronized silica is used as one of the most important raw materials in glass production.
  • Paint industry: Silica powder is used as a filler in the paint industry. It is also used as a filler in the production of polymer products.
  • Clothing industry: micronized silica is used as a filler and fire retardant in clothing production.
  • Food industry: Silica is used as an anti-heat agent, moisture absorption and preventing food from sticking to each other in food packaging.
  • Chemical industries: micronized silica is used as a filler and waterproof material in the production of chemical products such as paints, resins and rubbers.
  • Pharmaceutical industry: In the pharmaceutical industry, silica is used as a filler and absorbent.
  • Paper industry: In paper production, silica is used as a filler and reinforcement.
  • Textile industry: micronized silica is used as a filler and prevents fibers from sticking to each other in the production of different fabrics.

Powdered silica fertilizer and the advantage of using silica in agriculture

Powdered silica fertilizer actually contains silica powder (micronized silica) which is used as a soil conditioner in agriculture. This fertilizer contains heavy silica (more than 90% silica) or light silica (less than 90% silica).

Powdered silica fertilizer has the following properties:

  • By adding powdered silica fertilizer to the soil, the structure of the soil is improved and the soil uses more water and nutrients.
  • Powdered silica increases the resistance of plants to diseases and pests.
  • By using powdered silica fertilizer, the growth of weeds in the soil is reduced.
  • Powdered silica absorbs moisture, and as a result, the soil absorbs more moisture, which is beneficial for plant growth.
  • Powdered silica has the ability to absorb nutrients from the soil and thus is useful for improving plant nutrition.
  • By using powdered silica fertilizer, the productivity of agricultural products is improved.
