You can live without gold, you can live without diamonds, but certainly not without silicon and its compounds. If we search all of history, we will find less material that has made our world as dependent on it as silicon and its compounds. Today, silicone is used in the production of almost everything we use, from mobile phones and laptops to televisions and even children’s toys and doors and windows and car bodies and so on. It has applications and is a kind of industry development leader.
Micro silica powder is a by-product in the silicon production process. Exhaust gases from the furnaces are sent to the dust collection system. The output of the dust collection system will be clean air and micro silica powder. Therefore, no raw material will be used to produce micro silica powder. Micro silica is used in the production of cement (microsilica increases the strength and longevity of concrete). It is mainly used in cement and concrete industries and most of its customers are civil contractors and cement and concrete manufacturers. The resulting industrial products are of different types and cover a wide range of fields. They are known in the industry as magical products, so much so that in China, which accounts for about 64% of world production, this product is considered one of the pillars of China’s economic recovery. According to experts, the production of photovoltaic energy in the mid and late twentieth century will be one of the most important sources of primary energy for humans.Therefore, establishing a high base for large-scale industrial silicon production is of long-term strategic importance for photovoltaic power generation and even the regulation of the energy structure.
As the main product of the process, it is an extremely important and strategic product in the industry chain and is considered as one of the most practical upstream products in the industry. Is dedicated to itself. The resulting industrial products are of different types and cover a wide range of fields.

As mentioned before, the final product of the factory is silicon, which is in the category of industrial, mineral products information system of the country in the category of “manufacture of materials and chemical products / manufacture of basic chemicals except fertilizers / solid silicon” and the by-product of the factory (powder Micro-silica) also in the category “Manufacture of other non-metallic mineral products / Manufacture of other non-metallic mineral products not elsewhere classified / Types of non-metallic mineral powders / Micro silica powder”
According to the latest information received from the Ministry of Industry, Mines and Trade, the products studied in the project have the following ISIC code:
Silicon or Silicon (in French) with the chemical symbol Si is a chemical element of the quasi-metal family, which is in the fourteenth group and the third period of the periodic table of elements. It is a crisp, hard crystalline solid with a bright blue-gray color. The atomic number of this element is 14 and it has four electrons in the capacitance layer. The atomic mass of silicon is 28.086 and it has three stable isotopes. The reactivity of this element is less than non-metallic carbon of its class and upstream, but it is more reactive than its downstream germanium-like germanium.
The density of this material is about 2330 kg per cubic meter and in its natural state it is solid. Its melting point is about 1414 degrees Celsius and it has a boiling point of 2900 degrees Celsius.
Silicon is the eighth most abundant element in the world in terms of mass. Of course, it can hardly be found in pure and free form in nature. Silicon can be found mostly in dust, sand, asteroids and planets, and in the form of silicon dioxide or silicates. More than 90% of the Earth’s crust is made of silicate minerals, which is why silicon is the most abundant substance in the Earth’s crust after oxygen (about 28% by mass).
Most commercially used silicon is used without any separation and very little is processed on its natural composition. The same approach is used in the construction industry and ceramic production when using clay, sand and siliceous stones. Silicates are used in Portland cement to make mortar, plaster, and cement, and by mixing with siliceous sand, they are used to make concrete. Another application of silicon in the manufacture of some white ceramics, such as porcelain, is traditional lime glass with a quartz base and.. Silicon carbide is one of the more modern compounds of silicon or silicon, which is used as an abrasive in the manufacture of high-strength ceramics. The element silicon or silicon with written form (SILICON) is the basis for making widely used synthetic polymers called silicone, with written form (Silicone) or polysiloxanes.
The specifications of silicone are presented in the following table:
Most free silicon is used in the steel refining, aluminum casting, and many sensitive chemical industries (such as smoked silica). Less than 10% of silicon is used to make semiconductors. This highly refined silicon (perhaps of high purity) may play the most important role in the world economy because the electronics industry, the manufacturing of circuit chips, and therefore the construction of most computers depend on it.
Silicon is also a very important element in biology, although very small amounts appear to be required in animals. Many species of sea sponges require silicon for their body structure. Also, silicon and silicic acid play a vital role in the metabolism of plants, especially many grasses.
