Silicon Slag is a by-product of silicon metal’s production. It contains large content of  silicon and impurities of other elements. Some of the silicon content are elemental and some are silicon oxide.

Silicon Slag or Briquette is a good deoxidizer in molten steel deoxidization, meanwhile it can also purify the liquid steel. For its low price and good effect, steel-mills use it as a substitute of ferrosilicon. Regular size are powder at 0-5 or 0-10 mm. It can also been used to reproduce silicon metal or trichlorosilane.

Silicon Briquette is made from silicon slag powder, they are with similar features and applications. Besides, it can be produce into different sizes, and the content can be adjusted according to requirement. Meanwhile, the briquette shape also provides better melting speed in liquid steel or iron.

Advantages:

Si Slag or Si Briquette are much cheaper than ferrosilicon or other deoxidizers. It will significantly reduce the production cost;

Not like the other standard products, the chemical composition of Si Slag or Briquette is adjustable according to the customers’ requirement. So does the sizing.

Silicon Slag and Silicon Briquette are not classified into silicon metal or ferro-silicon. So there’s no import duty or anti-dumping duty against it. So it is easier for importers to handle in certain regions.
