Abstract:
The silicon extracts of quartz glass in different alkali solutions were systemically tested by Inductively Coupled Plasma Atomic Emission Spectra( ICP-AES) . The results showed that the silicon extraction in solutions with either single or mixed alkali solutions were agreed fairly well. That is, the extract amount of silicon in solutions of NaOH or KOH was more than that in LiOH under the same cond-i tions. The extract amount of silicon in the NaOH solution was a little more than that in KOH. Therefore, the different character between LiOH and NaOH、KOH under the same conditions explains why alkali aggregate reaction could be suppressed by lithium compounds.
