High-Performance Refractory Ceramics Of Percolated Mullite From Waste Materials

With the exponential increase in energy consumption owing to rapid industrial growth, there has been an associated significant increase in waste materials production from thermal power stations. In coal-powered stations, large volumes of coal combustion products are produced, including fly ash, bottom ash, and cenospheres. Fly ash is the fine fraction transported by flue gases and collected in electrostatic precipitators; bottom ash is the larger particulate ash that settles at the bottom of the boiler; and cenospheres are hollow fly ash particles. This article looks at high performance refractory ceramics of percolated mullite from waste materials.
