| Abstract: | The effect of preparation proceeding of high-purity silicasol reference material on stability was introduced. According to physical and chemical property of high-purity silicasol, the main factors such as pH value, particle distribution and electrolyte were studied. Mmeasures were taken to maintain the stability of high-purity silicasol , which solved the problem of stability of high-purity silicasol component reference material. The reference materials can keep steady more than one year. |
