摘要
本文研究了发射光谱法测定Fe2 O3 、Al2 O3 、CaO、MgO、MnO、NiO、TiO2 和火焰光度法测定K2 O、Na2 O ,然后以差减法得出SiO2 含量。实验结果与氢氟酸挥发法测定结果及外检结果相符。
Determination of Fe 2O 3, Al 2O 3, CaO, MgO, MnO 2, NiO, TiO 2 with emission spectrum method and determination of K 2O, Na 2O with flame photometric method were studied. The content of SiO 2 was got by difference method. The test results were in agreement with the results determined by hydrofluoric acid volatilization method and the results determined by other institutes.
