silicon slag briquette

Silicon Briquette is made from silicon slag powder, they are with similar features and applications. It can be produce into different sizes, and the content can be adjusted according to requirement. The briquette shape also provides better melting speed in liquid steel or iron, so as to avoid loss on ignition and provide better absorption rate.



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 can be used as 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.

New Silicon Briquette is also made from by-product, the cutting-down fine powder of high purity silicon products. Sometimes people call it silicon mud. Or silicon powder. It contains much higher silicon and much less impurities of other elements. Most of silicon content are elemental and little are silicon oxide. It performs perfectly as deoxidizing agent in metallurgy, even with same absorption rate with ferrosilicon, but with cheaper price. Since the silicon content is higher, the silicon briquette which produced from it were also with higher purity. The highest percentage of silicon can be up to 80%. But the size of this new silicon briquette are smaller than regular Si slag briquette. The particles of it are very small and so the space between particles are more in quantitative terms. Thus the weight of this briquette is light. Microscopically the silicon slag powder particles are not close enough. All the other physical and chemical properties are same, also CAS number, HS code are same with other silicon briquette.
