Metal silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Metal silicon is a product produced by smelting quartz and coke in an electric furnace, with a main component silicon element content of about 98%, and other impurities such as iron, aluminum, and calcium.
In China, metallic silicon is usually classified according to the content of the three main impurities, namely iron, aluminum, and calcium. According to the percentage content of iron, aluminum, and calcium in metallic silicon, it can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101, etc. In each grade, the first and second codes represent the percentage content of iron and aluminum, while the third and fourth digits represent the calcium content. Therefore, 441 represents the content of iron, aluminum, and calcium in metallic silicon, which is 0.4%, 0.4%, and 0.1%.
The characteristics of the Metal Silicon 441.
Chemical composition: Metal silicon 441 has the highest silicon content, reaching approximately 98.5%.
Physical properties: Metal silicon 441 has high conductivity and thermal conductivity.
Usage: Metal silicon 441 is widely used in fields such as electronics, optoelectronics, and semiconductors.
