In view of mullite and quartz crystal have less activation in fly ash, the different of calcining experiments are carried on, the different types of zeolite are synthesized. The experiments prove the method of addition alkaline when alkaline calcinations is better, and also research on its mechanism of activation, the temperatures of calcination and phenomenon of agglomerates，etc. Keywords: Fly ash。 Methods of addition alkaline。 Hydrothermal preparation。 Zeolite。 Species4 / 4
