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.So the content of iron, aluminum, and calcium in metal silicon represented by 421 is 0.4%, 0.2%, and 0.1%.Metal silicon 421 is a metallurgical metal silicon product.
The characteristics of the Metal Silicon 421.
Chemical composition: The silicon content of metal silicon 421 is about 98.5%, and it also contains high impurities such as aluminum, calcium, and iron.
Usage: Metal silicon 421 is mainly used as a deoxidizer, alloy additive, etc. in the metallurgical industry.
Production method: Metal silicon 421 adopts slag reduction method.
