Market Dynamics

Market Driving Factors

Increasing Demand for Aluminum-Silicon Alloys (Al-Si alloys) to Impede the Market Growth

Regarding industrial applications, aluminum is alloyed with other metals to enhance the natural benefits of aluminum products. Aluminum is used in a variety of applications. When combined with silicon, aluminum can form an alloy used to produce a material that accounts for the most significant casting-manufactured materials. These alloys have a wide range of applications in the automotive and aerospace industries because of an exceptional combination of castability, mechanical properties, good corrosion resistance, and wear resistivity. This is because they are also resistant to wear and corrosion. The mechanical properties of the alloy can be improved by the addition of minor alloying elements like copper and magnesium, and the alloy can become more responsive to heat treatment.

Developing components that are lighter in weight without compromising their strength is the most effective way to achieve these goals as a material designer. Energy savings and pollution control are two goals that a material designer should strive for on an ongoing basis. As a consequence of this, Al-Si alloy is the material that is most frequently used in the aerospace industry and the automotive industry, the marine industry, and the defense industry. Al-Si alloy possesses excellent castability and weldability, high fluidity, a low thermal expansion coefficient, high specific strength, reasonable wear and corrosion resistance, and recyclability. Aluminum silicide and silicide-magnesium alloys are frequently used in shipbuilding and the production of parts for offshore platforms due to their low weight, resistance to corrosion, and excellent mechanical properties. 

Number of Applications for Silicon Metal to Drive Market

Wafers of silicon are typically manufactured with the help of polysilicon, a by-product of silicon metal. Wafers made of silicon are the primary material used to produce integrated circuits, which are the structural backbone of most modern electronic devices. These devices include everything from consumer electronics to electronic systems used in industry and the military. Automakers have been forced to concentrate on developing their designs for electric vehicles due to the proliferation of electric vehicles in the mainstream automotive market. It is anticipated that this trend will lead to an increase in the demand for automotive electronics, which are expected to offer novel opportunities for the market for semiconductor-grade silicon metal. The rollout of 5G networks has been gaining steam in the telecommunications industry. In addition, developments in autonomous vehicles and the Internet of Things (IoT) have increased the demand for integrated circuits based on silicon. 

Market Restraining Factors

High Cost of Production to Hinder Market Growth

In a Submerged Arc Furnace (SAF), a specific heating system is used to make a variety of ferroalloys using electrical power; silicon metal is produced. For example, it has advantages like easy maintenance and high productivity. A large portion of the total production cost is attributed to the energy used in the SAF's smelting process. Quartz, the raw material used in silicon metal production, must be available continuously. Few global players control the mining of quartz, which comes from ores. New players will find it challenging to afford quartz because of this. Any variation in the supply or cost of raw materials is expected to impact production. As a result, silicon metal production costs are heavily influenced by the amount of energy and carbonaceous reductants used.

Conventional methods of refining silicon to produce high purity require large amounts of electrical and thermal energy inputs. A kilogram of silicon produced using the Siemens method requires up to 200 kWh of electricity, which is more than double the amount used. Refining silicon at a high enough purity level requires a lot of energy. Because of their high cost, Silicon metal production costs are expected to restrain the market's growth during its forecast period. However, the price of silicon metal will likely have little effect on the market's growth during this forecast period, as silicon metal plays a significant role in the global manufacturing chain.  

Key Market Opportunities

Rising Efforts to Lower the Cost of Production to Spur Market Opportunities

Conventional refining methods produce high-purity silicon and require significant electrical and thermal energy inputs. As a result, these methods have a very high energy requirement. For instance, the Siemens method requires temperatures higher than one thousand degrees Celsius and can use up to two hundred kilowatt-hours of electricity to produce one kilogram of silicon. Because of these energy requirements, refining silicon to a sufficiently high purity is costly. Therefore, there is a need to develop silicon production methods that require significantly less energy and are consequently cheaper.

Electro-refining is a new process that researchers at Arizona State University have developed. This process is used to produce ultrapure silicon. This method uses a two-step and three-electrode approach to deliver ultrapure silicon directly from metallurgical-grade silicon. It avoids using the standard Siemens process, which has several drawbacks, including the presence of corrosive trichlorosilane, a high energy requirement, and a high price tag. This process effectively removes impurities from metallurgical-grade silicon, resulting in silicon with ultrahigh purity greater than 99.99999 percent. This process requires only 20 kWh of energy input to produce one kilogram of ultrapure silicon, which is a 90 percent reduction compared to the energy input required by the Siemens method. The decrease in energy costs alone amounts to $10 for every kilogram of silicon saved. The production of solar-grade silicon metal is one possible field where this invention could be applied.
