摘　　要：结合粉煤灰的性质及化学元素组成,综述了粉煤灰在制备白炭黑、沸石、水处理和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。Based on the nature and chemical elements of fly ash, this paper stated new ways and value-added fly ash utilization in aspects of preparing silica, zeolite and water treatment as well as recycling rare metal. Currently, fly ash is mainly applied in construction, transportation and other industries. Though it could promote the utilization rapidly in a short time, they still are low value-added products, and fly ash does not give full play to the potential value. In the future, vigorously developing the value-added fly ash products will become the main direction in the study of utilization of fly ash.
