Abstract: A new method to prepare ZnO crystal was put for, ward. The preparation process was studied and the mechanism of this method was also discussed. The results show that the sol particles will aggregate when being dehydrated and will form into hard compact gel body through the hard agglomeration between particles. This dry gel is a hard compact agglomeration composed of the first sol particles. At high sintering temperature, the small compacted particles will easily grow up and form a fine ZnO crystal.
Key words: ZnO; sensitive ceramics; crystal; sol-gel
