What is the difference between silicon powder and silica fume

Many people confuse metallic silica powder with silica fume and think they look the same.So is the real situation like this? Let me give you the difference between the two of them today.

Silicon metal powder

Metallic silicon is divided into lumps and powders.Silicon metal powder is made by grinding silicon metal into powder.In general, users buy silicon metal, is to want the metal silicon block.But there are also users who want metallic silicon powder.

The function of silicon metal powder is the same as silicon metal, there are different brands, such as 553, 441, 3303, 2202, 1101 and so on.It is mainly used for the production of organic silicon, the manufacture of high purity semiconductor materials and the preparation of special purpose alloys.Grade and specification of silicon metal>>

Silica fume

Silica fume, don't look like metal silicon. But the method of making it is completely different. Micro-silica fume is an industrial electric furnace in the process of melting industrial silicon and ferrosilicon at high temperature, and the soot that escapes with the exhaust gas is collected and processed by a special collecting device.Grade and specification of silica fume>>

The particle size of fumed silica is very fine, the composition is mainly silica, the adhesion is large, and it is not easy to settle. Microsilica fume is generally used in mortar and concrete, such as high-rise buildings, reservoir dams, harbor terminals, railways, highways, bridges, etc.

After reading the above introduction, do you have any understanding of silicon powder and fumed silica? ALOY produces various specifications of silicon metal, silicon metal powder and micro silica fume, affordable price, excellent quality, best choice for you!
