| Abstract: | Amorphous SiO 2 is prepared by sol-gel process with chemical reagents of ethyl silicate, alcohol and distilled water. The microstructure and phase transformstion behavior of amorphous SiO 2 were investigated by means of TG-DTA, XRD and SEM methods. The phase transformation behavior is discussed themomechanically and dynamically. |
