Silicon metal, well known as crystal silicon or industrial silicon, is mainly used in the metallurgical industry as an alloying agent.

According to the content of iron, aluminum, and calcium, silicon metal is divided into different types such as 553, 441, 3303, 2202, 1101, etc.

On July 29, 2022, the price of silicon metal in the Chinese market fell slightly this week. Silicon metal 553 and off-grade silicon fell relatively significantly. Market demand is weak, and some purchases were made at the end of July, but lots of buyers are still on the sidelines. It is expected that the metal silicon market will be weak and stable in early August 2022, and it is expected that polysilicon orders will support the price of metal silicon 553.

Factors That Affect Silicon Metal Prices

Raw Materials: Industrial silicon is used silica and carbon reducing agents as raw materials. The content of iron, aluminum, and calcium in the raw material is strictly controlled. The price of silica and carbon affects the production cost of silicon metal.

Energy cost: Silicon metal is smelting in the electric furnace. The energy consumption accounts for about half of the total cost of the product. Therefore, silicon metal enterprises are located in areas with abundant power resources. During the wet season (from June to September), the electricity cost is lower, while the electricity cost is higher during the dry season (from November to April).

Supply and demand: Metal silicon 553 is mainly used in the production of organosilicon, highly purified conductor material, and silicon-containing alloys. In July 2021, the Chinese government limited production and electricity in order to achieve the goal of carbon neutrality, resulting in a reduction in the production of silicon metal, and many silicon metal factories stopped production. However, the domestic and foreign demand for silicon metal has increased, causing the price of silicon metal to soar.

Chemical composition and particle size: The silicon metal 553 is one of the most popular grades for domestic and foreign customers. The content of silicon reaches 98.7%, which can meet metallurgical needs, and the price is significantly lower than 441/3303. We can supply silicon metal lump (10-60mm), silicon metal powder (200mesh or as per customer’s requirement)
