Do you all know about silicon germanium? Now Xiaobian will introduce it to everyone!

Silicon germanium is a better deoxidizer and desulfurizer. During the deoxidation process, the three elements of silicon, calcium and barium promote each other, which effectively improves the utilization rate. Silicon germanium can lower the oxygen content in steel, and the recovery of silicon, calcium and antimony is higher than that of other alloys.

Silicon germanium alloy is a high-efficiency long-acting inoculant and steel-making strong deoxidizer commonly used in the production of ductile iron. Its mass fraction is 0.6%~40%, and the quality of silicon is 40%~70%. There are many analytical methods, usually determined by the gravimetric method of barium sulfate or separated from the interfering elements by the precipitation of barium sulfate. The determination by EDTA and titration is continued. In the acetic acid-sodium acetate buffer solution, ammonia triacetic acid is used as the chromium. Acid bismuth, separated from coexisting interfering elements, dissolved in bismuth chromate with dilute hydrochloric acid, titrated with ferrous sulphate standard solution, and the content of strontium is determined by method. The method has good reproducibility and the recovery rate is more than 99%. The relative standard deviation is 0.27%.
