| Abstract: | The silicon was turned into K_2SiF_8 Precipitate in strong acid medium and then let this precipitate dissolve into the solution of NaOH. After that, potassium was determined by atomic absorption spectrograph. Then, the silicon content in the cement was determined indirectly. The method is highly sensitive and fast. Standard deviation of fourteen determinations was 0.23, the coefficient of variation was 1.2%. |
