Regarding the chemical composition of metallic silicon, most people think that it only contains silicon. Most of the substances formed in nature are not single substances. So what is the chemical composition of metal silicon? Next, Hensfate Metal will share with you in detail:

What is the chemical composition of silicon metal

How to obtain metallic silicon?

Quartz is one of the most widely distributed minerals on the earth's surface and the main mineral component of silica. Contains 46.70% silicon. Coke is a kind of solid fuel with high calorific value, which is made by high-temperature dry distillation of coal. It is mainly used for ironmaking. Silicon metal is a product made by smelting quartz and coke in an electric furnace.

There are lumps and powders of silicon metal. Some customers need silicon blocks, while other customers need metal silicon powder. It depends on the customer's requirements.

Chemical composition of silicon metal；

In metal silicon, silicon as the main element can often reach 97%-99.79%. The other elements are iron, aluminum and calcium. Silicon metal is divided into different grades due to different needs. Such as 553, 441, 3303, 2202 and so on. Metallic silicon grade specification>>

These grades are named according to the iron, aluminum and calcium content of silicon metal. Take 553 as an example:

The iron content of the chemical elements of the metal silicon 553 is 0.5%, the aluminum content is 0.55%, the calcium content is 0.3%, and the silicon content is 98.5%.

I believe that after reading the above introduction about the composition of metal silicon, you must have a general understanding；

The downstream of metal silicon mainly includes silicon alloy, organic silicon, polysilicon and so on. In terms of alloys, metal silicon is used to produce silicon aluminum alloy, copper silicon alloy, and silicon steel. High-silicon aluminum alloy is a binary alloy composed of silicon and aluminum. It is a promising electronic packaging material, especially in high-tech fields such as aerospace, space technology and portable electronic equipment.

The above is about the sharing of the chemical composition of silicon metal, I hope it will be helpful to everyone. If you have any questions, you can leave a message in the message area below, or send an email to us, the team of metal silicon manufacturer will reply you as soon as possible；
