摘　　要：结合粉煤灰的性质及化学成分组成,综述了粉煤灰在制备白炭黑、沸石、水处理和在稀有金属回收方面的高值应用的新途径和应用现状。粉煤灰目前主要应用在建筑、交通等行业,虽然能在短时间内快速提高利用率,但均为低附加值产品,并未充分发挥潜在的价值,大力开发粉煤灰的高附加值产品是今后粉煤灰资源化利用技术研究的主要方向。Began with an introduction of the features and chemical composition of pulverized coal ash,this paper demonstrated the value-added utilization approaches and current status of pulverized coal ash in silica production,zeolite production,water treatment and rare metal recycling.At present,pulverized coal ash is mainly utilized in building and transportation,which presents a high utilization rate,low value,and great potential.So it is a principal direction for technological research to explore high value-added products by pulverized coal ash.
