摘要:
采用电感耦合等离子发射光谱法 (InductivelyCoupledPlasmaAtomicEmissionSpectra ,简称ICP AES)系统测试了石英玻璃在不同碱性条件下的硅溶出情况 .结果表明 :在单一或混合碱性溶液中 ,石英玻璃中的硅溶出表现出较为一致的规律 ,即 :石英玻璃中的硅在NaOH或KOH条件下的溶出量远远大于相同条件下的LiOH溶液 ;相比而言 ,硅在NaOH溶液中的溶出量大于其在KOH溶液中的溶出量 .在相同条件下 ,LiOH表现出与NaOH、KOH不同的性质特征 ,这为锂盐抑制碱集料反应的作用机理提供了一定的证据
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.
