A method of extracting a silicon-aluminum composite refractory material from fly ash
A method of extracting a silicon-aluminum composite refractory material from fly ash is disclosed. Traditional fly ash activation mainly adopts a mixed calcinating manner and is high in energy consumption. According to the method, fly ash is firstly mixed with an activating agent and water, and activation effects can be achieved in short time at a low temperature by an ultrasonic treatment manner. Extraction rates of silicon and aluminum can be effectively increased. An added auxiliary agent can effectively improve material compatibility, and enhance stability and fire resistance of a finished product. The method can be applied to steel, nonferrous metals, glass, cement, ceramics, petrochemicals, machines, boilers, the light industry, electricity, the military industry, and other fields of national economy, and is nontoxic, pollution-free, safe and environmental friendly.
