Application
1. Industrial silicon powder is widely used in refractory materials and powder metallurgy industry to improve the high temperature resistance, wear resistance and antioxidant properties of the products. Its products are widely used in steelmaking furnace, kiln and kiln furniture.
2. Silicon wafers processed by silicon powder are widely used in high technology field. They are indispensable raw materials for integrated circuits and electronic components.
3. In metallurgical industry, industrial silicon powder is used as a non-iron base alloy additive and silicon steel alloy, so as to improve the hardenability of steel.
4. Industrial silicon powder can also be used as a reductant for some metals, and it is used for new ceramic alloys.
Quality control system
Huarui has strict quality management system. We test our products first after we finish our production, and we test again before every delivery, even sample. And if you need, we would like to accept third party to test. Of course if you like, we could provide sample to you to test.
Our product quality is guaranteed by Sichuan Metallurgical Institute and Guangzhou Institute of Metal Research. The long term cooperation with them can save a lot of testing time for customers.
