High-purity silicon powder is a non-toxic, odorless, non-polluting inorganic non-metallic material. Because of its excellent properties such as good temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, stable chemical properties, and high hardness, it is widely used in chemicals, electronics, integrated circuits (IC), electrical appliances, and plastics. , Paint, paint, rubber, national defense and other fields. With the rapid development of high-tech fields, silicon powder will also enter a new historical development period.

Silicon powder is made of natural quartz (SiO2) or fused quartz (amorphous SiO2 after high temperature melting and cooling of natural quartz), which is crushed, ball milled (or vibration, jet milling), flotation, pickling purification, high-purity water treatment, etc. Micro powder processed by the process.

Significantly improve compression resistance, flexural resistance, impermeability, anti-corrosion, impact resistance and abrasion resistance; it can retain water, prevent segregation, bleeding, and greatly reduce the resistance of concrete pumping; significantly extend the service life of concrete, especially in chloride salts Pollution erosion, sulfate erosion, high humidity and other harsh environments can double or even increase the durability of concrete; greatly reduce the ash of sprayed concrete and castables, and increase the thickness of the single spray layer; it is high-strength concrete Necessary ingredients; it has about 5 times the effect of cement, and can reduce costs when used in ordinary concrete and low-cement castables. Improve durability; effectively prevent the occurrence of concrete alkali aggregate reaction; improve the compactness of castable refractories.

Silica powder should be distinguished from silica fume as crystalline silica;

Micro silicon powder is amorphous silicon dioxide. It is a kind of ultrafine silicon powder material formed by the rapid oxidation and condensation of SiO2 and Si gas produced during the smelting of ferrosilicon alloy and industrial silicon and oxygen in the air.

The above is the high-purity silicon powder that the editor tells you that it is a non-toxic, odorless, non-polluting inorganic non-metallic material. You can simply understand it. The content is for your reference only, you can contact our manufacturer if you need to know about it.
