  • Synthesizing Mullite from Beneficiated Fly Ash

    Fly ash is a by product of coal combustion. U.s. power plants generate approx­ imately 50 million tonnes of fly ash each year.1.2 Currently, only about 20% of the fly ash is utilized3 4 primarily in the cement industry. The remaining 80% is landfilled, which can cause environmental problems. One study summarized fly ash impacts on
