Introduction of Silicon Metal Power
Silicon metal powder refers to raw material applied in refractory materials and powder metallurgy industries. Silicon metal powder is made of silicon metal (also called crystalline silicon or industrial silicon). The silicon metal uses are as an additive to non-ferrous alloys. However, silicon metal is made of quartz and coke in an electric furnace. The content of silicon is about 98% in the main component (the content of Si 99.9% is also contained in silicon metal in recent year.). And the remaining impurities are iron, Aluminum and Calcium and so on.
High Temperature Resistance
Silicon metal powder can be used in the production of refractory materials and powder metallurgy industry. The silicon metal powder can improve the high temperature resistance of the product during smelting, which is usually required by the steel industry.
High Durable
The silicon metal powder can improve the wear resistance of the castings in the production of some wear-resistant castings. The silicon metal powder uses can effectively improve the service life and quality of the castings.
Deoxidation
The silicon metal powder contains a certain amount of silicon which can affinity-produce oxygen to produce silica, and reduces the reaction ability during smelting while deoxidizing. It make sure deoxidation much safer!
Silicone Industry
The silicon metal powder can participate in the synthesis of silicone polymers. And we can produce high quality silicon monomer, silicone rubber, silicone oil and other products through silicon metal powder.
Metallurgical Foundry Industry
In the metallurgical foundry industry, silicon metal powder has also been widely used. In the steel making process, silicon metal powder can be used as a deoxidizer, alloy additive and so on. And the effect is very significant. Meanwhile, the silicon metal powder can also be used in the production of castings as inoculant uses.
Applications And Uses of Silicon Metal Power
Silicon Powder Properties
Silicon is a chemical that has similarities to carbon and tin. It is considered extremely hard and brittle. It does not react to water, oxygen, or acids as this stability makes it ideal for a range of applications where the other base metals or applications must maintain their original characteristics in varying environments. The silicon expands when it freezes, and bonds with varying metals and other chemicals to create a uniform seal. It is also a reinforcing agent, and resists corrosion and oxidation. When in powdered form, the chemical is waterproof, tolerates high temperatures well, and offer electrical insulation.
To create silicon powder, silicon lumps are broken up and milled into specific grain sizes. Some main applications for silicon powder include the following:
Adhesives & Coatings
Silicon powder has excellent bonding capabilities, making it ideal when used in sprays and coatings on varying surfaces to create a sure bond. It also prevents corrosion and oxidation due to having no reactions to waters or acids.
Silicone Rubbers, Oils, and Resins
When it comes to synthetic materials, silicon powder is highly used. It is the basic metal for silicone rubbers, resins, and oils due to its water resistance, temperature tolerances, and electrical insulation properties.
Lubricants
Silicon powder offers anti wearing and anti-aging properties. It is placed in lubricants and oils as the silicon allows the liquids to flow smoothly over metal surfaces. It forms into a film over the parts to provide enhancements to friction performance.
Semiconductors
Silicon is used in integrated circuits throughout the semiconductor industry. The powder offers thermal stability created from electrical fields and operating systems so components function without experiencing changes to their mechanical or structural properties.
Refractory Materials
Silicon offers refractory properties to processes that require the use of constant high temperatures or pressures. It may be used as a lining for iron smelting processes or mud water cannons as it resists wear, temperatures, and oxidation.
Silicon Metal Powder Production Method
There are many methods for producing finished silicon metal powder from silicon blocks. The effect is better, and the application is more: ball milling, roller milling, and spinning.
Its main equipment: ball mill, roller mill, puncher
The first two are crush honing under gravity. The latter is the impact of fine crushing. Various mills can process and pulverize non-flammable and explosive minerals with a Mohs hardness of less than 7.0. The finished product size is regulated by the process. It is controlled in the range of 30 mesh (0.613 mm) to 425 mesh (0.033 mm).
The appearance of metallic silicon is taupe. It is a shiny, hard and brittle silicon block. Silicon symbol Si. The atomic number is 14. Atomic weight: 28.0355. The atomic radius of silicon is 1.17 μm.
The Difference Between Silicon Metal Powder And Silicon Powder
Metal silicon powder
Use:
- Metal silicon powder is widely used in refractory materials and powder metallurgy industries to improve the high temperature resistance, wear resistance and oxidation resistance of products. Its products are widely used in steelmaking furnaces, kilns and kiln furniture.
- In organosilicon chemical industry, metal silicon powder is the basic raw material for the synthesis of organosilicon polymers. Such as used in the production of silicon monomer, silicone oil, silicone rubber preservatives to improve the product’s high temperature resistance, electrical insulation, corrosion resistance, waterproof and other characteristics.
- Metal silicon powder is drawn into monocrystalline silicon, and the processed silicon wafer is widely used in high-tech fields, and is an indispensable raw material for integrated circuits and electronic components.
- In the metallurgical casting industry, metal silicon powder is used as a non-ferrous alloy additive and a silicon steel alloy agent to improve the hardenability of steel. Industrial silicon can also be used as a reducing agent for certain metals, for new ceramic alloys, etc.
- After washing, selecting, grinding and processing into 200-mesh, 320-mesh fine powder, it can be divided into 92%, 95%, 97%, 98% and other quality standards according to the content, and the price is low. In the process of refractory materials, different specifications can be selected according to the requirements of refractory products, thereby greatly reducing the cost of refractory products.
Silica powder
Performance:
Silica fume, also known as silica fume, is the dust recovered from the production of metallic silicon or ferroalloy. Because the silicon dioxide contained in silica powder is very high and the particles are small, it is widely used not only in rubber and coating industries, but also in concrete and other industries! Silica fume is pozzolanic active.
Use:
- Control the segregation and bleeding of concrete materials, reduce or avoid defects such as honeycomb, pitted surface, weak interlayer, cracks and milk skin in concrete.
- Improve the compressive strength of concrete. Experiments have shown that silica fume can greatly improve the strength of concrete.
- Improve the durability of concrete, improve the impermeability, frost resistance, wear resistance and corrosion resistance of concrete.
- Improve the carbonation resistance of concrete. For reinforced concrete, the unfair incorporation of silica fume can improve the bonding strength between the matrix and the steel bar, and can also enhance the corrosion resistance of the steel bar.
- Improve the fluidity and density of refractory materials, and improve the high temperature strength and thermal shock resistance of refractory materials.
Silicon Metal Powder Processing
The particle size processing process of silicon metal powder includes the following steps:
Crushing: Crush the selected ore into particle sizes suitable for further processing.
Screening: Screen the crushed stones to separate particles of different sizes for further crushing and processing. The screening process can use a screening machine to carry out screening and classify particles according to prescribed standards to achieve the expected quality requirements.
Crushing: Particles of different sizes are fed into the crusher for crushing. There are many types of pulverizers to choose from, such as ball mills, Raymond mills, and ring roller mills, each with its advantages and disadvantages. Factors such as processing temperature and humidity need to be strictly controlled during the crushing process to ensure that the powder quality meets the expected requirements.
Drying: To ensure the dryness of the silicon powder, it needs to be dried. The drying process requires controlling parameters such as temperature and time to achieve the appropriate degree of drying.
Packaging: The dried silica powder can be packaged and stored. Packaging materials generally take the form of plastic bags, cardboard boxes, iron drums, etc. During the packaging process, attention must be paid to sealing and moisture-proof measures to ensure product quality.
