Ferrosilicon is often used as a deoxidizer in steelmaking because silicon combines easily with oxygen to form silicon dioxide. Furthermore, the formation of silica releases a large amount of heat, which also helps to raise the temperature of the steel.

Ferrosilicon is an alloy of iron and silicon (average content is 15% to 90%). It is a key ferroalloy used for deoxidation and alloying of steel. Silicon increases the hardness, tensile strength, elasticity and flow limits of steel, improves oxidation resistance and reduces energy losses.

In steel making: Used as Deoxidizers and alloying agents
In ferro alloy production: Used as reducing agent
In Foundry: Used as Inoculants and spheroidizing agents

High-purity silicon metal is used by many industries. In the chemical industry it is used for producing silicon compounds as well as silicon wafers used in photovoltaic solar cells and electronic semiconductors. And aluminum manufacturers use it to improve the already useful properties of aluminum. When used with aluminum, silicon improves its castability, hardness and strength.

Besides, aluminum demand has been growing steadily in recent years, as a reflection of the economic activity in both the developed and developing word. This demand of lighter and more economical material has triggered a growth in Silicon metal consumption by aluminum manufacturers.

That said, silicon compounds are the raw material for a large and growing number of industrial and consumer products such as:

Silicone rubber parts
Urethane foam
Sealants
Adhesives
Lubricants
Food additives
Coatings
Polishes and cosmetics

Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys.

Metallic silicon is a product made of quartz and coke smelted in an electric furnace. The content of the main component silicon is about 98%, and the other impurities are iron, aluminum, calcium, etc.

In industry, silicon metal is usually produced by reducing silicon dioxide by carbon in an electric furnace. Chemical reaction equation: the purity of silicon prepared by SiO2+2C Si+2CO is 97 98%, which is called metallic silicon. Then it is melted and recrystallized, and impurities are removed with acid to obtain metallic silicon with purity of 99.7~99.8%.
Metal silicon particles: 1-200mm

silicon metal should be used to produce organic silicon, produce high-purity semiconductor materials and prepare alloys with special purposes.

(1) Production of silicone rubber, silicone resin, silicone oil and other silicone.

(2) Manufacture high-purity semiconductors.

(3) Prepare alloy.

(4) It is an excellent antioxidant in refractory and powder metallurgy industries.

Our company can provide various specifications and models of metal silicon blocks, particles and powders according to customer requirements.

ferro silicon nitride powder is applicable to stainless steel smelting, special alloy steel smelting, oriented silicon steel smelting and other casting industries.

As a new type of refractory material, it is applied in the metallurgical field, such as metallurgical furnace body, furnace mouth seal, ironmaking furnace outlet, iron hook amorphous material and nitrogen additive in the steelmaking industry.
Silicon nitride material can be used as abrasive material for abrasive tool manufacturing, and can also be used in chemical fields such as acid resistance, alkali resistance and corrosion resistance.
In terms of steelmaking, granular ferro silicon nitride is mainly used in the production of oriented silicon steel at the initial stage, and it can stably supplement a certain amount of nitrogen for molten steel.
