1. The difference in the production process of silicon powder and micro silicon powder

Silica powder is made of natural quartz (SiO2) or fused quartz (amorphous SiO2 after natural quartz is melted and cooled at high temperature), crushed, ball milled (or vibration, jet milling), flotation, pickling and purification. High purity water. Fine powder processed by traditional technology. Micro silicon powder (also called silicon powder or agglomerated silicon powder) is a kind of ferroalloy. When ferrosilicon and industrial silicon (silicon metal) are smelted, a large amount of highly volatile SiO2 and Si gases are generated in the geothermal electric furnace. After oxidation and condensation with air, it will precipitate out. It is a by-product of large-scale industrial smelting. The entire process requires the use of dust removal and environmental protection equipment for recycling, because it is lightweight and requires encryption equipment for encryption.

2. The difference in appearance between micro silicon powder and micro silicon powder

In terms of appearance, silicon powder and silicon powder are also relatively easy to distinguish. Silicone powder is pure, white and balanced. It is a non-toxic, odorless, non-polluting inorganic non-metallic material. According to the raw material and reducing agent of silica, or different furnace conditions, most of the micro silica fume is gray or dark gray. During the formation process, due to the effect of surface tension in the phase change process, amorphous spherical particles with an amorphous phase are formed, and the surface is relatively smooth, and some are aggregates of multiple spherical particles bonded together. White micro silica is rare.

3. The difference in performance and use of silicon powder and micro silicon powder

According to the performance or function of silicon powder and silicon powder, silicon powder generally has excellent temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, stable chemical properties and high hardness. performance. According to the application, silicon powder is divided into the following categories: ordinary silicon powder, electrical grade silicon powder, electronic grade silicon powder, fused silica silicon powder, ultrafine quartz silicon powder, nano silicon powder, etc. Aosite is a professional manufacturer of silica powder, welcome to inquire.
