Why is metal silicon 441 used in the metallurgical industry
ZhenAn metal silicon 441 manufacturers know that the additional products of metal silicon include edge silicon, silicon powder, black silicon, metal silicon slag, etc. Among them, microsilicon powder is also called silica fume, silica powder or silica fume, which is widely used in concrete industry and refractory materials. The main component of metal silicon powder is crystalline silicon. Its shape is initially blocky and the color is relatively stable. After a series of crushing or grinding work, it is powdery and generally inactive.

Generally, sodium hydroxide is used as a catalyst to dissolve silicon powder to prepare silica sol, that is, silica sol with a silicon dioxide content of more than 30% and a yield of more than 80%, also called silicic acid hydrosol or silica hydrosol. It has a wide range of applications in precision casting, catalyst carriers, papermaking, textiles and other industries. The preparation method of metal silicon powder is simple and easy, and the preparation principle is easy to understand. After dispersion, a certain amount of coarse silicon powder is sent into the plasma arc with inert gas, so that the coarse silicon powder is instantly evaporated into silicon vapor at a higher temperature, and then the silicon vapor enters the cooling zone and condenses into other nano-scale metal silicon powder. Some impurities will be produced during the production of metal silicon powder. To obtain pure metal silicon, impurity removal must be done well. Metal silicon has high purity and is industrially purified elemental silicon. It is mainly used in the production of silicon and the 3C industry. In addition to preparing high-purity semiconductor materials, it can also be used to make alloys for special purposes. When purchasing materials, you must also choose a reliable manufacturer.
