In the vast world of modern industry, metal silicon – shining star of modern industry, also known as metallic silicon or crystalline silicon. It was born from the encounter between silica and carbonaceous reducing agent. In the embrace of the submerged arc furnace, it experienced a chemical transformation and gained new life. Silicon material has become the darling of many fields due to its excellent physical and chemical properties.
Metal Silicon in Modern Industries
For the photovoltaic industry, metal silicon is the cradle of polysilicon. Polycrystalline silicon is one of the key materials for solar cells, which determines the efficiency and cost of solar cells. As the global demand for renewable energy increases, the market demand of the solar photovoltaic industry is rapidly expanding, driving the growing demand for high-quality metal silicon. However, the purity and quality of metal silicon directly affect the production efficiency and cost of polysilicon. Silicon 553, 521, 441 and some low boron and low carbon models can be raw materials for polysilicon. Improving metal silicon production technology and optimizing its production process have become important issues in the industry.
Metal silicon is an indispensable alchemist in the alloy industry. For example, in the world of alloys, metallurgical grade silicon metal, like silicon metal 553, silicon metal 441, silicon metal 3303, etc., are like skilled craftsmen, integrating silicon elements into alloys to give them stronger strength and harder bones. and more wearable skin. It is also like a wise man who improved the casting and welding skills of metal, making the alloy stronger and stronger. In addition, silicon, as a deoxidizer, can remove oxygen from the melt and purify the metal solution.
Chemical grade silicon models, such as silicon metal 421, silicon 411, can be material of silicone. Silicone has the characteristics of high temperature resistance, corrosion resistance, and good insulation. Opportunistic products made of silicon metal are widely used in construction, cosmetics, medical and other fields. As the largest consumer channel of metal silicon, organic silicon has maintained an average annual growth of more than 10% for many years.
Metal Silicon – Shining Star of Modern Industry: Consumptions
China is a major producer, consumer and exporter of metal silicon in the world. In 2022, my country’s metal silicon production capacity and output will account for 79% and 78% of the world respectively. And its consumption will reach 3.132 million tons (including exports). With the proposal and implementation of our country’s “carbon peaking and carbon neutrality” goals, the photovoltaic industry’s demand for metal silicon will exceed 1.9 million tons in 2025. So, it is estimated that by 2025, China’s metal silicon demand will reach 4.8 million tons. The market size will approach 100 billion yuan. This indicates that metal silicon – shining star of modern industry will continue to play a pivotal role in green energy.
