Silicon Metal 551

Metallic silicon, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. Metallic silicon is smelted from quartz and coke in an electric furnace and contains about 98% silicon. Silicon metal is mainly composed of silicon and therefore has similar properties to silicon. Silicon has two allotropes: amorphous silicon and crystalline silicon.

Metallurgical Product Description

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.

Product Advantages

Manufacture And Use

Metallic silicon is used to produce organic silicon, prepare high-purity semiconductor materials, and prepare alloys for special purposes.

(1) Produce silicone such as silicone rubber, silicone resin, and silicone oil.

(2) Manufacturing high-purity semiconductors.

(3) Prepare alloy.

Applications

It is widely used in refractory materials and powder metallurgy industries to improve its heat resistance, wear resistance, and oxidation resistance.

In the field of silicone chemical industry, industrial silicon powder is the basic raw material of silicone polymers.

Industrial silicon powder is sublimated into single-crystal silicon, which is an important raw material for integrated circuits and electronic components and is widely used in high-tech fields.

In the metallurgy and foundry industries, industrial silicon powder is used as an iron-based alloy additive and an alloying agent for silicon steel to improve the hardenability of steel.

Used in high-temperature material production to make enamels and pottery. These also serve the needs of the semiconductor industry by producing ultra-pure silicon wafers.
