| Abstract: | It was explained the theory in detal of the determination of content of sodium oxide and silicon oxide in the sodium silicate.A improved method to measure the content of silicon oxide was described on the basis of analysis and the problem of current methods.The content of silicon oxide can accurately determinate through adding the supersaturated solution of NaF and the end point was easily got by the pH meter in the experiment.The calculated modulus of sodium silicate was more accurate and more repeatable. |
