The advantages of metal silicon powder as a refractory material

Features of metal silicon powder:

1. High temperature resistance

Metal silicon powder has strong high temperature resistance, so adding an appropriate amount of metal silicon powder many times in the production of refractories and powder metallurgy can greatly improve the high temperature resistance.

2. Wear resistance

Usually we add metal silicon powder in the production of some wear-resistant castings to improve the wear-resistant performance of the castings.

3. Deoxygenation

Metal silicon powder, as the name suggests, contains a certain amount of silicon, which can have an affinity with oxygen to form silicon dioxide, which reduces the melting reactivity during deoxidation and ensures the safety of deoxidation!

In addition, metal silicon powder has also been widely used in the metallurgical foundry industry. In steelmaking, metal silicon powder can be used as deoxidizer, alloy additive, etc., and the effect is very obvious.

Silicon fume and metal silicon fume are two completely different products. In practice, these two products are often confused because they are inextricably linked.

The silica fume we usually say is also called silica fume and micro silica fume. It is the soot recovered from the production process of metal silicon or ferroalloy. Due to its high content of silica, extremely fine particles and high activity, it can be used in concrete, refractory materials, rubber, paint, etc. There are a wide range of applications in industries such as.

The main component of metal silicon powder is crystalline silicon (Si). Its initial form is lumpy, and it becomes powder after being crushed or ground, which is used in industries such as refractory materials.

The reason why metal silicon powder is turned into powder is because it is physically ground, and silicon powder is naturally formed during the production process.

The chemical composition varies greatly. Silicon powder is mainly silicon dioxide, and the main content of metal silicon is SI element.

Metallic silica fume is generally inert, while silica fume is a pozzolan. The color of metallic silicon powder is usually relatively stable, while the color of silicon powder varies greatly from white to black. Silica fume is widely used. The price of metal silica fume is very high, several times that of micro silica fume
