What is Metal Silicon

Metal silicon, also known as silicon metal, is often a type of alloy that is made from silicon and other metals, such as aluminum, iron, and copper. It is a gray, metallic material that is known for its high electrical conductivity, good corrosion resistance, and high melting point.

Metal silicon is rarely pure silicon. Pure silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, brittle, crystalline solid that is a good conductor of electricity and is widely used in the semiconductor industry for the production of microchips and other electronic components. Pure silicon is not typically used in the same applications as metal silicon, as it does not have the same mechanical properties and is not as resistant to corrosion.

 

How is metal silicon produced

Metal silicon, also known as silicon metal, is produced through a process called reduction, in which silicon dioxide, also known as silica, is reduced to pure silicon using a reducing agent, such as carbon or hydrogen. The production process involves several steps, including:

Preparation of raw materials

The first step in the production of metal silicon is the preparation of the raw materials, which include silica, the reducing agent, and any other alloying elements that are to be added to the final product.

Reduction

The raw materials are then placed in a furnace and heated to a high temperature, typically around 2,000-2,500°C (3,632-4,532°F). The reducing agent is then introduced into the furnace, and a chemical reaction occurs that reduces the silica to pure silicon.

Casting

The resulting molten silicon is then poured into molds and allowed to cool and solidify. The resulting ingots are then cut into the desired shape and size.

Refining

The resulting metal silicon may be further refined to remove impurities and improve its properties, such as its electrical conductivity or corrosion resistance.

It is important to note that the exact process used to produce metal silicon may vary depending on the specific requirements of the final product and the equipment and technology available at the production facility.

 

What is metal silicon used for

Metal silicon is used in a wide range of applications, including:

Electronics

Metal silicon is used in the production of electronic components, such as transistors, diodes, and microchips, due to its high electrical conductivity and good corrosion resistance.

Solar panels

Metal silicon is used in the production of solar panels, as it is a good conductor of electricity and is able to withstand high temperatures.

Alloys

Metal silicon is used as a raw material in the production of various alloys, such as aluminum-silicon alloys, which are used in the automotive and aerospace industries.

Other

Metal silicon is also used in the production of castings, as a deoxidizing agent in steel production, and as a catalyst in the production of polysilicon, which is used in the semiconductor industry.

It is important to note that metal silicon is highly reactive and can ignite when it comes into contact with water or other materials. It should be handled with caution and protective gear, such as gloves and goggles, should be worn when working with it.

 

What types of Metal Silicon are there

There are several types of metal silicon, each with slightly different properties and applications. Some common types include:

Silicon Metal

This is the purest form of silicon, with a minimum purity of 99.99%. It is used in a wide range of applications including electronics, solar cells, and metallurgy.

Ferrosilicon

This is an alloy of silicon and iron that is used primarily as a deoxidizer in the production of steel and other ferrous alloys. It also serves as a source of silicon for the production of silicon steel.

Silicon Bronze

This is an alloy of copper and silicon that is used in a variety of applications including electrical components, gears, and marine hardware.

Silicon Carbide

This is a hard, brittle material that is used in abrasives, refractories, and as a semiconductor.

Silicon Nitride

This is an extremely hard and heat-resistant ceramic that is used in high-performance applications such as aerospace, automotive, and power generation.

Trace elements are sometimes added to silicon to form specialized alloys that have specific properties, depending on the application requirements.

These are some of the common types of metal silicon, there are other specialized types as well which are used in specific industrial or research applications.

 

Market and trade information

The global metal silicon market is a large market for the production and sale of metal silicon and metal silicon-based products.

According to a report by MarketsandMarkets, the global metal silicon market is expected to reach a value of $6.2 billion by 2022, growing at a compound annual growth rate of 7.9% from 2017 to 2022. This growth is driven by increasing demand for metal silicon in various industries, including electronics, solar energy, and metallurgy. The report also notes that the Asia-Pacific region is expected to dominate the global metal silicon market, due to the increasing demand for metal silicon in the region and the availability of low-cost feedstock.

China is the largest producer of silicon metal in the world. According to statistics, China is responsible for about half of the world’s production of silicon metal, followed by Russia, Norway, and the United States. The large production of silicon metal in China is due to a number of factors, including a large domestic market for the metal, low labor costs, and government support for the industry. Additionally, China has abundant resources of silicon raw materials, which help to keep production costs low. However, it’s worth noting that the global market can be subject to fluctuations and changes in the short term.

According to https://oec.world/ :

Ferro-silicon, >55% silicon are the world’s 1057th most traded product.

In 2020, the top exporters of Ferro-silicon, >55% silicon were Russia ($364M), China ($303M), Norway ($295M), Brazil ($226M), and Malaysia ($210M).

In 2020, the top importers of Ferro-silicon, >55% silicon were Japan ($345M), Netherlands ($275M), Germany ($241M), South Korea ($199M), and India ($176M).
