Silica, also known as silica, silicon dioxide, is one of the most abundant natural substances found in nature. This substance is known by the chemical formula SIO. You can find this substance freely in nature. Silica alone is used in many cases, which we will discuss more in this article. We intend to talk about topics such as the reaction of silica with carbon and other properties and applications of silica.
What is silica?

As mentioned, silica is one of the most abundant natural substances in nature. In addition to the fact that silica can be used as an industrial material in many industries, we can see it in some foods. The presence of silica in our body is very necessary, that's why its deficiency can lead to many diseases in the body. Of course, consuming too much of it can also be dangerous.

Silicas are found in nature in different forms, such as crystalline, secret crystal and juicy secret crystal, each of which has different uses. The most consumption of silica is in hard industries. This material has a lot of hardness and resistance, that's why we say that it is used the most in industries.
Mechanism of reaction of silicon with carbon to produce silicon carbide

Several mechanisms have been defined for the production of silicon carbide (SiC) using the reaction of silicon (SiO2) and carbon (C) at high temperatures. Among these mechanisms, some cases in the temperature range of 1500 have been widely accepted. up to 2000 K.7-9 However, due to the complexity of this reaction, there is no complete investigation to obtain this mechanism, based on thermodynamics and kinematics of this reaction.

Silica carbon reduction reaction using thermodynamic concepts and by fitting the relevant models, the experimental data obtained for this reduction was investigated using a thermogravimetric unit in the temperature range of 1566 to 1933 degrees Kelvin.
The results show that the only way to produce SiC in this reduction is the reaction of Si, SiO, or SiO2 on the surface or the diffusion of SiO inside the carbon particles, while CO and CO2 have no direct effect on the process.
The controlling step of this reduction at temperatures below 1750 K is the gas-solid or solid-solid chemical reaction on the surface of the carbon particles, while at higher temperatures, the rate of SiO diffusion inside the carbon particles controls the rate of this reduction.
Properties and applications of silica

As we said, Silica can be used in many cases, one of the most important cases in which we use Silica is in agricultural land and planting rice. The use of silica in the soil of agricultural lands, as well as the soil we use to plant rice, increases its quality and helps them grow better. If your plant is withered or does not photosynthesize, it can be detected that it lacks silicon.

Among the other uses of silica, we can refer to industries such as glass making, sand-lime brick production, ceramic making, sodium production, casting, glazing, electronic industries, rubber and plastic making, water treatment, cement, industrial cleaners, paint and Covering, flotation of ore, casting mold, gluing, etc.

As we said, silica is one of the essential substances that is needed in the body, as the lack of silica in the body leads to a series of diseases such as arthritis, teeth strengthening, and bones. Note that the presence of this substance in the air when you breathe in it can enter your lungs and damage it. One of the most important cases in which silica is used is making toothpaste, because this substance has abrasive properties, we can use it in toothpaste.
The price of pure silica

Due to the fact that silica is one of the pure materials that are used in various industries, there are different types of silica with different qualities that you can buy any type according to your needs and field of work. .

    Micronized silica
    First grade silica
    Second grade silica
    premium silica
    Water purification silica

The last word about the reaction of silica with carbon!

The production and sale of first-class and high-quality silica has many stages, and its production process must be done well by companies. The importance of updating the devices needed to produce this mineral is also very important. Hamadan Diamond Powder Company is proud that it has been able to take over the majority of the sales of this product, both inside the country and in neighboring countries. Consultation and guidance in product purchase, production and sale of minerals (silica, calcium carbonate, dolomite, feldspar) is one of the main activities of this company. To buy silica and other products and minerals of this company, contact our experts or register your purchase order through the purchase form.
