Generally, sodium hydroxide is used as the catalyst, and silica powder dissolution method is used to prepare silica sol, that is, silica content of more than 30%, yielding more than 80% of silica sol, also known as silicate hydrosol or silica hydrosol, which has been widely used in the industries of precision casting, catalyst carriers, papermaking, textile and so on. The preparation method of metallic silicon powder is simple and easy to understand the preparation principle.
Through the dispersion, a certain amount of crude silicon powder with inert gas into the plasma arc, so that the crude silicon powder at a higher temperature instantaneous evaporation into silicon vapor, and then the silicon vapor into the cooling zone, in the nanoscale condensation into other silicon metal powder, silicon metal powder production process will produce some impurity components. To obtain pure silicon metal, it is necessary to do a good job of removing impurities. Silicon metal has a high purity and is an industrially purified monolithic silicon. It is mainly used for the production of silicon, which is applied in 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, we should also choose a reliable manufacturer. The quality of materials produced in our factory is guaranteed. Please give us a call for inquiries.
