Determination of Silica Content in Rare Earth Ferrosilicon Alloy and Rare Earth Ferrosilicon Magnesium Alloy

Graphical Abstract

Abstract

Abstract

The samples were dissolved in the mixture of HNO_3-HF. Saturated KNO3 were added in K2SiF6. After K2SiF6 hydrolyzed with boiling water, the content of silica can be determined with NaOH standard solution by titration.
