| Abstract: | In view of the high content of silica in fly ash and abundant heat in blast furnace slag, high efficiency silicon fertilizer was prepared by mixing blast furnace slag with fly ash directly. When the fly ash and blast furnace slag were mixed with a mass ratio of 7.76:92.24, the effective silicon content in silicon fertilizer was highest after the condition of quenching. With increasing slag temperature, the effective silicon content in silicon fertilizer increased, and the effective silicon content of silicon fertilizer can reach up to 22.4% at the slag temperature of 1 550℃. Finally, the preparation technology for high efficiency silicon fertilizer with blast furnace slag and fly ash was raised. |
