2mm ferro silicon barium alloy is a multi-element ferro alloy with a size of 2mm. The ferrosilicon barium alloy is mainly composed of three elements: silicon, barium and iron. Silicon is a non-metallic element that can increase the strength and other properties of steel in steel; barium is an alkaline earth metal that can play a role in deoxidation in alloys; iron, as the matrix of the alloy, carries other elements to play a role.

2mm refers to the size of the alloy particles. This smaller size helps to better mix and react with other substances when used. Generally speaking, the silicon content in ferrosilicon barium alloy may be 40%-60%, the barium content is 15%-25%, and iron is the balance. However, the specific composition will vary depending on the production process and application requirements.

Chemical properties

Deoxidation

Because barium has a strong affinity with oxygen, ferrosilicon barium alloy can react with oxygen in a high temperature environment to generate barium oxide, thereby playing a deoxidation role, which can effectively reduce the oxygen content in materials such as steel.

Stability

At room temperature, silicon iron barium alloy has good chemical stability and is not easy to react chemically with oxygen, moisture, etc. in the air. However, chemical reactions may occur under specific conditions such as high temperature, humidity or strong acid and alkali.

Products uses

Steel smelting:

It is an excellent deoxidizer and alloy additive that can combine with oxygen in steel to form barium oxide compounds, reduce the oxygen content in steel, and improve the quality and performance of steel. At the same time, silicon and barium can also form alloys with other elements in steel to improve the mechanical properties, hardness, wear resistance, corrosion resistance, etc. of steel.

Foundry industry:

As an inoculant, it is suitable for gray cast iron and ductile iron, which can promote the formation of "A" type graphite and make the graphite spheres complete. At the same time, it can form nuclei in a wide temperature range, and has strong spheroidization ability and anti-degradation ability, which can effectively prevent the tendency of castings to white cast iron.

Other fields:

It has good chemical stability and corrosion resistance, and can be used in the chemical industry as a material or additive for some chemical equipment. In addition, it also has certain applications in the electronics field and can be used to manufacture certain semiconductor materials.
