Arabic Silicon metal is cleaned, selected, and ground into fine powder of 20 mesh to 600 mesh. According to the content, it can be divided into 90 metal silicon powder and 95%, 97%, 98%, 99.99% and other quality standards, and the price is low.
In the process of producing refractory materials, different specifications can be selected according to the requirements of refractory materials, thus greatly reducing the cost of refractory materials.
Silicon metal powder can be mixed with other materials such as alumina, magnesia, and zirconia to form refractory materials with specific properties. For example, silicon metal powder can be added to alumina to improve its thermal shock resistance and increase its refractoriness. In addition to its use in refractory applications, silicon metal powder is also used as a raw material in the production of other refractory materials such as silicon nitride (Si3N4) and silicon oxynitride (SiAlON).
Silicon metal powder is typically stored in a dry, cool place to prevent oxidation and degradation of its properties.

Packaging Details: Waterproof Plastic woven bag, 1mt or 1.25mt big bag, and also can customize as customer required.
Delivery Time: Within 30 days of receipt of advance payment.
Storage:
Silicon powder should be stored in a dry and cool place to prevent moisture and heat from affecting its quality. The area should also be well-ventilated to prevent the buildup of flammable gases.
Silicon powder is stored in containers labeled and marked with appropriate information, including the product name, batch number, date of manufacture, and handling instructions and can prevent contamination, moisture, and exposure to air.
Application
1.Steel industry:
A large amount of silicon metal is used for smelting into ferrosilicon alloy, and it is also a reducing agent in the smelting of many kinds of metals. Silicon metal can replace aluminum in the steelmaking process, improve the efficiency of deoxidizers, purify molten steel, and improve the quality of steel.
2.Aluminum alloy:
Silicon is also a good component in aluminum alloys, and most cast aluminum alloys contain silicon.
3.Electronics Industry:
Metallic Silicon is the raw material of ultra-pure silicon in the electronics industry. Electronic devices made of semiconductor silicon have the advantages of small size, lightweight, good reliability, and long life.
4.Chemical industry:
Silicon metal is used to produce silicone rubber, silicone resin, silicone oil and etc. Silicone rubber has good elasticity that can be used to make medical supplies and gaskets. Silicone resins are used to produce insulating paints, high-temperature coatings, etc.
