Silicon Slag is a by-product of silicon metal production. It's the separated part which are less purity of silicon metal. Usually silicon slag contains higher contents of Fe, Al, Ca and other oxide. Silicon, with other elements like Fe, Al, Ca, have strong reaction with oxygen; Meanwhile other impurities are oxide also are not harmful to liquid steel. Those characters made silicon slag to be a great de-oxidizer. Huatuo metallurgy is professional silicon slag supplier in China with high quality, competitive price and high reputation. Welcome to visit our factory.

Silicon slag is a kind of colloid polymer with high water content with yellow green appearance, strong adsorption and complicated structure. The main ingredients are silicate and water, it shows acidic after water immersion, PH < 1, the solid content at 20%.

Silicon slag can not only be used for producing white carbon black, after processing but also be used as cement materials or making ordinary firebrick. Silicon slag can be recycled through recrystallization and purification again to realize silicon material use again make silicon slag fully used. The recycle value is relatively high.

Application

1. The silicon slag is much cheaper than 99% purity silicon metal, and has many industrial applications.

2. It is Used as deoxidizing agent in steel production to reduce oxygen levels in the melt via reaction. Use as deoxidizing agent in the production of magnesium, chromium and other metals via the same mechanism;

3. The silicon slag powder can be made silicon briquette which has far and wide market at home and abroad.

Advantage

1. Silicon slag has a much lower price than ferrosilicon so it can greatly reduce the production cost in steelmaking.

2. We have our own factory, so we can Guarantee the lowest price on time delivery, the best quality, the most timely after-sales service.

3. Sample will be provided free of charge.

4. Third-party test such as SGS / BV.

5. Customized according to customer’s needs
