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.
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%.
