Microsilica
Microsilica is the fume generated during silicon metal production process, the fume are collected by the filtration system and reproduced and densified to become the byproduct. It is used as additive for the concrete, it enhance the fluidity, strength, permissibility, corrosive protection of the concrete.
Microsilica Specification
SiO2 >90%
CaO <1.0%
Al2O3<0.5%
C < 1.0%
Quartz
Quartz and carbon materials are the main raw materials used for silicon metal production and the keys for the high purity silicon metal production is the quartz. G.S.Energy owns two high quality and rich reserves (22 millions mt) quartz mine for own use and sale.
Off Grade Silicon (Deoxidizer)
Off grade silicon is a byproduct of silicon metal production process. It can be used in steel production as a deoxidizer.
Chemical Composition
Si >20% Fe <0.5% Al <10% Ca <15%
