Analysis methods for SIO2 in the glass industry
Thread Content
Are there any of you in the glass industry? Please share the methods you use for working with SiO2. This post was last edited by Canghai Yili Sha on 2009-2-23 at 19:48.]
Is the question from the original poster about the analysis methods for silica in the glass industry? I’ll change the title.
Do you have any good methods? I hope you can offer some advice

My wife works in glass analysis; I’ll ask her for you when she gets back
We all conduct measurements in accordance with the national standards for the analysis of glass and raw materials. Different analysis methods are used depending on the SiO2 content. For contents above 90%, the evaporation method is used, mainly for silica sand in sandstone. Secondly, the potassium fluosilicate capacity method is used, primarily for the analysis of glass composition. For those with lower contents, the silicomolybdenum yellow colorimetric method is used.
