由于SiC中的总硅量高达70%左右,所以用500μg/100ml的标准SiO2溶液作为参比溶液,以硅钼蓝示差分光光度法测定SiC超细粉末中的总硅量。
Because the total silicon content in SiC amounts is about to 70 % , We have taken a standard solution containing SiO2500 μ / 100ml as a reference solution to determine the total Si content in SiC by differential spectrophotometry of silicon - molybdenum blue .
