摘　　要：采用微波消解碱溶法对粉煤灰中硅铝的溶出规律进行了研究,考察了粉煤灰热处理温度、碱浓度、溶出时间、溶出温度等因素对粉煤灰中硅、铝溶出量的影响。并将微波消解与压力反应釜实验进行对比。This paper studied the rules of dissolved silicon and aluminum from fly ash by microwave-heating alkaline solution in low temperature. The principle of microwave-heating is introduced. The factors of pretreatment temperature of fly ash, alkali concentration, leaching time and leaching temperature are investigated .The results compared with that by pressure leaching are better in leaching effect.
