The difference and connection between micro silicon powder and metal silicon powder

Jun 09, 2022 / 470 views
Silicon powder and metal silicon powder are two completely different products. In actual use, these two products are often confused because they are different and related.
What we usually call silica fume, also known as silica fume and micro-silica fume, is the soot recovered in the process of producing metallic silicon or ferroalloy. It is widely used in rubber, paint and other industries.
The main component of metal silicon powder is crystalline silicon (Si). Its initial form is bulk, and after crushing or grinding, it becomes powder, which is used in refractory materials and other industries.
Their main differences are:

1. The reason why metal silicon powder becomes powder is through physical grinding, and silicon powder is naturally formed in the production process.

2, the chemical composition is very different. The silicon powder is mainly silicon dioxide, and the main content of metal silicon is SI element.

3. Metal silica fume is usually inactive, while silica fume has pozzolanic activity.

4. The color of metal silicon powder is usually relatively stable, while the color of silicon powder varies greatly from white to black.

5. Silicon powder has a relatively wide range of uses.

6. The price of metal silicon powder is very high, which is several times that of silicon powder.

Their main connections are:

Silica fume is the soot recovered during the production of metallic silicon
