Silicon metal powder 200 mesh 98.5% The silicon content is 98.5%, and the content of other impurities is relatively small. In industrial applications, such purity can meet a variety of production needs, such as metallurgical casting, organic silicon chemical industry and other fields. 200 mesh indicates the size of the silicon metal powder, that is, the number of holes on the sieve per inch is 200, and the corresponding size is about 0.075mm. The finer size enables it to be better mixed and reacted with other substances in various applications, giving full play to its performance.

Usually, the lump of silicon metal is processed by crushing, grinding and other processes. Common production methods include Raymond milling, roller milling, disc milling and whirling milling. Different production methods will affect the microstructure, specific surface area, size distribution and surface oxidation of silicon powder, and thus affect its chemical reactivity.

Application fields

Metallurgical casting:

As a non-ferrous alloy additive and silicon steel alloying agent, it can improve the hardenability of steel and improve the performance of steel. In the casting process, it helps to improve the quality and performance of castings.

Organosilicon chemicals:

It is the basic raw material for the synthesis of organic silicon polymers, used to produce silicon monomers, silicone oils, silicone rubber preservatives and other products, which can improve the high temperature resistance and electrical insulation of these products. Thermal insulation, corrosion resistance, waterproof and other characteristics.

Refractory materials:

can improve the high temperature resistance, wear resistance and oxidation resistance of refractory materials, so that they can be widely used in high temperature environments such as steelmaking furnaces, kilns, kiln tools, etc., and extend the service life of these equipment.

Electronic industry:

After further processing and pulling into single crystal silicon, it can be made into silicon wafers, which are indispensable raw materials for high-tech products such as integrated circuits and electronic components, and have important applications in the field of electronic information.

Quality standards

Generally, they must comply with relevant national standards or industry standards, among which the silicon content is not less than 98.5%, and there are clear restrictions on impurity content, such as iron not more than 0.6%.

In actual production and application, manufacturers will also formulate more stringent corporate standards according to the specific requirements of customers to ensure the stability and consistency of product quality.

Storage and transportation

Storage

It should be stored in a dry and well-ventilated warehouse to avoid moisture and rain to prevent silicon powder from oxidation or agglomeration, which will affect its performance. At the same time, it should be stored separately from oxidants, acids and other substances to prevent chemical reactions.

Transportation

Generally, it is in the form of ton bags.During transportation, care should be taken to prevent silicon powder from flying and leaking, and ensure that the transportation vehicle is well sealed. Usually, ton bags and other packaging forms are used to facilitate loading and unloading and transportation. At the same time, care should be taken to avoid collision with sharp objects to prevent packaging damage.
