摘　　要：研究了不同的活化剂和温度条件对石英砂中硅的促释效果。结果表明,选用的四种活化剂在不同的温度烘干条件下均对石英砂的活化有明显的作用。第一组活化剂中WZ的效果较好,且在35℃时优于60℃时的活化效果,石英砂中水溶性硅提高135.49%;第二组活化剂QN的效果最高,远大于第一组活化剂。促释技术为石英砂等含硅量高的矿渣研制硅肥提供了一条新的途径。The promoted-release effect of different activators on silicon in quartz sand on the condition of different temperature was studied in this paper.The result showed that these four activators could obviously activate the silicon in quartz sand at different temperatures.Among the activators in group one WZ was relatively good.Moreover,the activation effect at 35℃ was better than that at 60℃.The water-soluble was increased 135.49%.Among the activators in group two QN was the best,which is far better than group one.The promoted-release technology provides a new way for making silicon fertilize from quartz sand.
