The main component of metallic silicon is silicon, so it has similar properties to silicon. The properties of metallic silicon are similar to those of germanium, lead, and tin, and have semiconductor properties.

Silicon Metal 551 is processed by excellent industrial silicon and includes full varieties. Used in electro, metallurgy, and chemical industry. It is silver gray or dark gray powder with metallic luster, which is of high melting point, good heat resistance, high resistivity, and superior oxidation resistance, it's called "industrial glutamate", which is an essential basic raw material in the hi-tech industry. Silicon metal is usually classified according to the content of its three main impurities such as iron, aluminum, and calcium. Based on the content of iron, aluminum, and calcium, silicon metal can be divided into different grades such as 553, 441, 421, 3303, and 2202.

The main component of metallic silicon is silicon, so it has similar properties to silicon. Silicon has two allotropes: amorphous silicon and crystalline silicon. Amorphous silicon is a gray-black powder, which is a microcrystal. Crystalline silicon has the crystal structure and semiconductor properties of diamond, with a melting point of 1410°C, a boiling point of 2355°C, Mohs hardness of 7, and brittleness. Amorphous silicon is chemically active and can burn violently in oxygen. It reacts with non-metals such as halogen, nitrogen, and carbon at high temperatures, and can also react with metals such as magnesium, calcium, and iron to form silicides. Amorphous silicon is almost insoluble in all inorganic and organic acids, including hydrofluoric acid, but is soluble in a mixed acid of nitric acid and hydrofluoric acid. Concentrated sodium hydroxide solution can dissolve amorphous silicon and release hydrogen gas. Crystalline silicon is relatively inactive and does not combine with oxygen even at high temperatures. It is not soluble in any inorganic acid or organic acid but is soluble in mixed acids of nitric acid hydrofluoric acid and concentrated sodium hydroxide solution.

The properties of metallic silicon are similar to those of germanium, lead, and tin, and have semiconductor properties. The classification of metallic silicon is usually based on the content of the three main impurities of iron, aluminum, and calcium contained in the metallic silicon component. According to the content of iron, aluminum, and calcium in metallic silicon, metallic silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101.

Silicon metal 97 is the smelting material that is widely used in the smelting of aluminum ingot and special steel at present. It is a kind of good non-iron base alloy additive. The content of silicon metal 97 produced by zheng is as high as 99.99%.
